I think I , like most people in this thread, loved the game itself. Still love it, even with my issues with the ending.
Things I really enjoyed:
1) The gameplay. I'm a run and gun type of gamer, and ME1 let me do that perfectly. Loved not having to worry about ammo, just overheating my weapon. It gave me a great sense of power, and (as a huge Halo gamer as well) it felt comfortable. Of course, that meant I was playing it alot like I did Halo, staying out in combat until I was JUST ABOUT to die, then take cover so I could recharge. No real strategy required. ME2 I felt was too cover-based, but ME3 finds (in my opionion) the perfect balance.
2) The humour. Yes, this is a dark and brooding game where you're trying to resolve centuries-old conflicts and prejudices to enlist help to stop galaxy-wide genocie, but this had the most laugh out loud moments of any of the games! EDI joking about forgetting to recylce the O2, Ashley drunk in starboard observation, Male Shepard being shot down by Traynor... I thought it had a great balance between the tragic and hilarious.
3) The scenery. All of the worlds/stations/ships look great and feel natural. The ambient conversations really added to the immersion for me.
OK, so now I get to things I didn't like. Which is really, one thing:
The Ending.
Alot of people have posted their issues with the plot/lore/logistic issues witht he ending, so there's really no point in going over it again. I would like to offer my $0.02 though on how to amend the ending to something that I feel would be more in the vein of ME.
1) Options. Of course, none of the options we're presented are too desireable. We can only destroy all synthetic life, try to control the reapers, or force "synthesis?" I don't buy it. Regardless of how people have played their games, Shepard has always marched to the beat of his/her own drum. I feel that any Shepard, in this moment, would have looked at starchild and said "screw you, I have my own option..."
Of course, I'm a (hopeful) supporter of the Indoctrination theory, so that whole part kind of makes sense if you follow that.
Anyways, my issue with the ending is that, unless you use your imagination, you don't get any REAL sense of what actually happens after the choice. I believe that after I chose destroy, Shepard woke up in London after being hit by the blast, finds his team, and continues the fight with a clear mind. But how is that the end? It's a continuation.
And if you choose the other two options, then again, we're left with having to imagine the ending... but that's still a continuation, not a conclusion.
Now, I'm not a writed for Bioware, so, while I have my own opinions on what to do story-wise, I won't worry about putting them here. You can see one of my other posts if you're interested in that, I just don't feel like I have
So, in keeping with the theme of sacrifice, but also triumph, that I feel ME has really been grounded in since the beginning, I have a couple of ideas of how the game can be ended.
1) Fight the reapers, lose. You didn't have enough allies and/or resources, and what allies you had were still caught up in their own issues, and didn't work well together. You go to the endgame knowing you're outmatched, but hoping for a miracle. You don't get one. Reapers win, trillions die.
2) Fight the reapers, win, but at great cost, Shepard dies. Which is how I feel the current ending (even destory) is presented in-game. The Mass Relays are all destroyed (why?) stranding everyone where they are, a lot of people will die due to lack of usable resources and available food, but the Reapers have been stopped, the cycle has been broker. While there's a lot of bad happening, there's still a little hope that the future will be better, even if it's not for our character's children or even grandchildren, etc.
3) Fight reapers, win, less cost, Shepard still dies. A lot of people die, but the Citadel survives, Mass relays survive, but Shepard still had to sacrifice him/herself to get the job done. While no happy ending for Shepard, happy ending for the teammates of Shepard, providing they survive. Yes, everyone has lost someone dear to them in one way or another, but they're still alive, and they can help rebuild the galaxy in an era of tolerance and peace.
4) Fight reapers, win, Shepard lives, LI dies. Shepard has finished the fight, but winning took the sacrifice of *insert love interest here* There have been several times throughout the series that Shepard states that (s)he couldn't have done it without the team, what better way to show this than having the one person that means the most to Shepard have to give everything to help Shepard win?
5) Fight reapers, win, Shepard & LI live. While I'm a romantic at heart and REALLY want this ending, I feel like this should the kind of challenging to achieve, though it should still be an option. I personally feel that Shepard, for all his/her hard work and helping other people with their issues, is due a happy ending and a nice long vacation on a beach somewhere, with *insert color here* babies of whatever species running around.
However the story progresses or gets resolved with whatever content, or explanation of the endings, that comes out, these are the ending options that I feel best suit the feel/theme.
Of course, this is all just my opion, but that's what this thread is all about, right?
