Missed opportunities, quirkiness and moments that were just not as great as the rest of the game-The part where Grunt almost died and no-one caredI was baffled by the way Shepard ran away from the fight with the Rachnii, leaving Grunt and his crew behind, then calls out to Carlos that they are the last ones out. There is no hesitation, no remorse, no gried, nothing. They just -run away- from a loyal ally, a friend and his company of heroes who stayed behind to make sure Shepard could carry out his/her mission. They don't even look back. Fortunately, Grunt survived (not sure that always happens) but this should have been a moment that gave Shepard pause. He/she should be running, Grunt behind, not noticing he was falling back at the last moment, then realise something is wrong, try to help, only for Grunt to come running out on his own. Alternatively, he/she should slow down, turn around, then wait, take up defensive position or something, at least pause and -hope- for a miracle or at least show -regret- at believing he'd died.
-The part where Mordin dies needlesslyMordin dies because he goes into a tower that is exploding, knowing there is a bomb or whatever there, because he's the only one who can take care of it. However, as far as I could see, all he did was enter some data into a computer, which he might have done remotely as well. In any case, bringing a teammate along to defuse the bomb would have been a great idea. Mordin was awesome, even for a Salarian and he should be able to join Shepard for the rest of the ride unless there is a real, compelling reason for him to die.
-The part where Ashley almost made a comebackI liked Ashley in ME1, was hurt by the way she acted in ME2 and was happy to see her in ME3.. Until she kept questioning whether I was part of Cerberus. From the get-go. Then didn't let it go, even upto the point where she considered listening to Udina instead of to Shepard. So when she asked if she could be part of my crew? Per mission DENIED! GTFO. But after the way she sent some conciliatory messages in ME2, this seemed a bit like character assasination. Didn't we save the galaxy together once? Could we reduce these moments of doubt to one at the beginning, then have her reveal, in the hospital, that she hadn't been certain until she'd seen Shepard fight alongside her against the Cerberus forces on Mars.
-The part where Udina became councilorSo, I chose Anderson as councelor. Now he's back in uniform again, which is fine. But why? Was Anderson called back to duty? For what reason? Did this mean Udina got the job by default? Did no one else want it? Is this explained somewhere? Did I miss something?
-The part where Udina was a jackass/a fairly decent guy/a Cerberus cronyI hated Udina in ME1. I hated him in ME2 and loved the part where you could play it in such a way that Anderson slapped him into next week. Then in ME3 he turns out to be a fairly decent guy! He backs Shepard up, making the case for working together, then cashing in favours to get the war effort going even without his fellow councilors giving a helping hand. All of a sudden, he's a Cerberus crony and tries to get Shepard killed. WTF? Is this guy bi-polar or schizofrenic or something? What is -up- with him? If you're making him the bad guy, then go all the way and don't confuse me like that.
-The part where Kai Leng uses a medieval sword in the 22nd centuryI really disliked Kai Leng as he featured in the game. I kind of understand there has to be someone in a role like this, but I disliked how he took out Thane (one of the Galaxy's greatest assasins and basically a decent guy, unlike Zaeed) so easily. Thane was not his best, but he should at least have given Thane a run for his money and gutting someone with a sword is so... Medieval. I think that had something more to do with ME3 focusing more on melee (which I kept my Femshep out of as much as possible as she kept on dying, which is basically, well, bad) than with it making sense. This was especially noticable the few times Shepard fought Kai Leng, extremely so during the final battle with him, where you are -unable to do anything- until he's basically on top of you and you have to press F, F, F, in an effort to survive. I'm sorry, but my Femshep is a -soldier- with a wide variety of weapons and able to kill even Reapers at range. How does he get that close? If he were using an invisibility cloak or something, fine. But -walk up to my Shepard- and then try to gut her like a deer? How does that make sense? He would have been put down before having moved an inch. Get rid of the sword, give him a cloak, give him a background that makes it plain why he's so buddy-buddy with the IM and give him an actual personality.
-Why don't the powers carry over?After playing and replaying ME2, I had several cool powers, including Reave, which I got from Samara. In ME3? Gone. I basically only have ammo powers and even one power I haven't used, Adrenalin rush. I ended up removing all points allocated to that one and moved them to another one. When I tried to add Warp, I ended up losing armour-piercing ammo, which is quite useful against various baddies. So I decided to stick with what I had. But it makes no sense to me that powers aren't carried over from one game to the next (just as it doesn't make sense to me that importing faces doesn't work. My Femshep had a face in ME2, so what's the deal with that?). Reave was a cool power that I'd like to keep.
-Why can't I select my own squad?I spent most of ME2 recruiting a team, which means it was probably important. In ME3 it is good to see what happens to all of them, but shouldn't I have much more of a choice in deciding who I keep? What if I want Samara with me? Or Zaeed, with his inferno grenades? I don't like him much, but he's one mean SOB and a crack shot. I am able to talk the Geth and the Quarians out of continuing their long war, but I can't persuade a former teammember to join me? If they come with me, they may die, if they don't, they may still die but maybe even everyone dies. All of the people who joined in ME2 know what is at stake and must feel the urge to help Shepard make the universe safe.
-Why can't I get more love from Liara?Liara was my lover in ME1, I bought the Lair of the Shadow Broker DLC for ME2 moslty so we could at least do one mission together and loved the part where you could rekindle the relationship. In ME3, she basically acts as if that tender moment, all too brief, never even happened. Why?

She spends more time talking to others than to me? Most of the time she barely says hello? She shares a memory with me in London, but I don't even get to see what it is. All I saw was darkness and some light flashes. I even got scared for a second because her eyes went dark and I thought maybe the Reapers had gotten to her somehow.
-Killing a Reaper. Alone. Without backup.When Legion starts to wish Shepard luck when he/she decides to take on a reaper, by pointing a laser at it and facing the wrath of it's main gun on his/her own, I thought Legion was going to say she was crazy. There was no reason this could not be done from behind cover or with backup distracting the reaper just long enough or just by calling in how clos the strikes were coming, like you do with artillery. It was madness and Shepard ought to have died then and there. At least during the assault on the beam in London, Shepard was not alone.
-The kid and the slomo-thingSo, billions of people die, including one kid. One kid which we don't even see dying, we just see a shuttle taken down. We don't even know with 100% certainty no one survived that crash. Although it is incredibly unlikely, Shepard & co have survived much worse. So why is Shepard broken up about that kid, which he/she didn't even know and not about all the other people who died that meant something to him/her? If the kid had been Ashley's sister (and Ashley a sympathetic person, see above) or Anderson's son or daughter or something, fine. Also, what is with the slomo thing? If Shepard has to have a very annoying recurring dream, please allow me to do something or otherwise, allow me to skip it, at least the second time around. Same goes for walking up from the place with all the corpses in the Citadel, allow Shepard to catch a breath and run to help Anderson.
OMG, please -fix- this!Basically, ignore everything above if need be, but fix the end of this game. Otherwise I don't see how I can buy anymore games from Bioware, if you manage to screw up such a wonderful story in the end, how can I trust you to make any decent games in the future? Buying DLC or another game before this is fixed would be like buying another Paradox game, which I have vowed never to do again as all their games are delivered buggy as hell and then never are patched to a point where they work as intended, only for them to produce another game/expansion promising that they've done a better job/will do a better job of patching this time. Yeah right. I bought several of their HOI and EU games, but I won't anymore, for the above reasons. As a former US President once said: fool me once, shame on me, fool me.. you can't get fooled again!
-The Endings, OMG, the ENDINGS? Make it stop, make them go away!The final part of ME3 is a huge disappointment. Fortunately, I was prepared for it, because of all the spoilers here and elsewhere. Even so, it is just incomprehensible to me how -anyone- could have thought this was a worthy ending. Can someone just come out and say you guys ran out of time and just had to create an ending, any ending? Because that's the only reasonable explanation I can come up with. Please see below for several reasons why the endings are flawed and how to fix this.
1) I didn't even understand the choices the first time aroundFrom what I understood, I had three options:
A) Kill all artificial beings, including the Geth. -Didn't like that option after working so hard to get the Geth and the Quarians to stop fighting and it would have been hugely unfair to Legion, who sacrificed himself just so the Geth would see it his way and stop the war. That the kid/catalysts things biologicals and AI's will be at eachother's throats at some point is his problem, but the Reapers need to be stopped without the Geth sharing their fate.

Have Shepard take control of the Reapers, allowing him/her to force an end to the war. - Didn't like that option, but wanted to choose that one, because it would lead to the intended result: the Reapers stopped. Theoretically, Shepard could then force the Reapers to commit suicide by heading into the nearest star or something. That this would cost Shepard his or her life would be acceptable.
C) Join -all- biological and artificial lifeforms together
at the expense of the relay network. - Didn't like that option, because it basically means changing everyone alive and isn't that exactly what Shepard has been trying to prevent? Also, how would even the most advanced being/civilization be able to accomplish that feat in an instant?
Of course, for some reason, the Relay network goes down no matter what, which I failed to notice the first time around. In my defense, I was up late at night, having played the game into the early hours of the morning. But where is he option for Shepard to ask: can you repeat that? What was the question again, Trebek? How about PUTTING THE OPTIONS ON THE SCREEN LIKE YOU'RE HAVING A CONVERSATION WITH SOMEONE?
2) I didn't even know which way to go for whichever choice I madeFor some reason, I didn't follow that there were different colours and stuff, so I just assumed the pathways were in chronological order, with the third and final option in between, so basically, I thought the pathways led to options A, C and B, respectively. Which was confusing enough. Instead, they led to option B, C, A. Why? Is the kid actively trying to confuse a Shepard already about to faint from blood loss? In the end, I had to replay the ending just to get the ending I had originally chosen, only to notice they were basically the same.
3) The choices don't make senseAccording to the kid/catalyst AI and biologic beings will always go to war with eachother and AI will always win. Umm, no? AI are programmed and can be shackled. Also, who builds AI and then puts them in bodies which are able to carry weapons anyway? Also, what about the Geth? What about EDI? Both are now using Reaper code and -still- want to help biological beings defeat artificial life forms. There goes your theory right out the window. BTW, what are you doing by giving me options? You -lost- this war, remember? We have the largest fleet ever assembled working together and apparantly the Citadel is important to you as well, otherwise you would have destroyed it instead of trying to keep it safe. So, the moment this dawns on anyone (probably EDI and/or Joker) you are in for a rather unpleasant surprise.. Now shut up and die so we can live in peace. You can keep the relays, but please allow us all to go -home- first!
4) What is the kid even doing there?Who is the kid anyway? Why does he look like a kid and not like someone big and powerful and mature? What race is he from? Was he on the Citadel all along? Then why didn't he override whatever modifications the Proteans made that prevented the Reapers from coming back earlier? Do the Reapers have a leader? Is the Crucible a trap planted by the Reapers and the Catalyst as the final remaining piece a hidden flaw in the design? Then why didn't the Proteans detect this? How come they were able to program the Citadel but not find there was some being/AI there that would screw everything up?
5) The whole rationale behind the kid/catalysts motives are flawedIf the Geth and the Quarians can make peace and EDI can fall in love with Joker, than how inevitable is it that AI will fight biological being? If he/she/it feels sorry for the inferior biological beings, then why kill them and turn them into synthetic beings? Wouldn't any being created that way have some very horrible memories that will haunt the new being forever? Also, even if he/she/it is doing so out of a misplaced compassion, how does it defend the fact that, no doubt, millions are never harvested/ascended?
6) Liara? How did you end up on the Normandy?So I take Liara and Javik along to take out the Reapers. I take a wrong turn and end up on the Citadel. But Liara, who was one step behind me, ends up on the Normandy? Unhurt? How? Why would my lover abandon me under such circumstances? How did the Normandy end up so close to the beam thing that they could pick up Liara? If that was even possible... WHY NOT JUST DROP US OFF THERE IN THE FIRST PLACE?
7) Joker? Where are you going?So, Liara ends up on the Normandy somehow. As if that isn't enough, the Normandy is flying away from an exploding relay. But isn't the relay on the far side of the solar system? Wasn't the Normandy in London just moments ago? Just after it was attacking the Reaper fleet together with the allied forces?

And how do they end up on some alien Garden planet?
8) Don't exploding Relays take out entire systems anymore?So, the Batarians hated me for taking out one relay, which resulted in the Death of hundreds of thousands of people. Well, now -all- of them explode and all you have to do is fly away for a bit, then crashland on the nearest planet?
9) Who the hell is that Stargazer and why should I care?A story that spans three games and hundreds of hours ends with two characters we never met who tell us absolutely nothing useful? Why?
10) What happened to everyone?Who made it out alive? Who didn't? How many people died on Earth? Did someone build their own mass effect drive using Reaper/Protean knowledge and restart interplanetary commerce? After all, the Proteans built one to link Ilos with the Citadel, how hard can it be? What happened? Do you want me to buy DLC to find out? I think you do, considering the final lines on screen, but.. Really? After -this- ending? How do I know you won't do this again?
An ending that would have made sense:-The Reapers are bad, m'kay? They have killed billions of living beings and artificial beings for whatever purpose they have. It would make the most sense that they are simply beings who want to live -forever- at whatever cost, a goal that is stated in ME1 and which makes a kind of sense. The events of ME2, where it turns out they integrate those they conquer into their own fits into that mindset as well. Shepard would -never- be able to negotiate with these beings for the simple reason that there is no advantage to negotiating about whether you want to be killed or subjugated. The Reapers wouldn't even want to try, they are arrogant. They feel they are superior and seem to pity Shepard for not realising that biological beings are inferior and their own victory is inevitable. They would be confused/outraged Shepard got to the Citadel and would rather destroy it than taking the risk of anyone getting to it and using it as a weapon to annihilate them. BTW, wasn't the Citadel the key to the Reaper invasion plan? A conduit between wherever they come from and our Galaxy? What if it could be used the opposite way? Sending the Reapers away or destroying whatever save harbour they have/all Reapers remaining in that area? In short: one epic, final battle. Since the Reapers insist on being everywhere at once, a major strategic mistake, all the allied forces have to do is follow the established military doctrine of uniting their forces and attack in strength at a weak spot, then proceed to defeat the Reapers piecemeal. Unfortunately, Earth is not that place, so it made no sense that the allied forces seemed inclined to attack there. The Reapers take the Citadel there precisely because they have overwhelming force. Likewise, it makes no sense what Anderson says to Shepard, about sending him/her into the gut of the Reaper forces. Why? Can we have a quest for finding a copy of Art of War by Sun Tzu? Because I think they need it. Of course, they could have just made use of the confusion of a major fleet engagement and have landed Shepard & co directly on top of the Citadel. I'm sure if anyone can pull that off, it is Joker.
