Here is my opinion about Mass Effect 2. First off, I have to say that all in all I really love the game and played it through many times. Graphics and voice acting are great and the sound score is nothing short of excellent and sets the mood very well. The story is very interesting and combat is fast paced and deadly. I really enjoyed the experience and always keep coming back for another playthrough. There are a few things that I would like to see improved in the sequel, so here are my 2 cents so to speak:
CLIP SIZE/ AMMO CARRYING CAPACITY
I am not opposed to the idea of introducing "ammo" back into the game, but I think the developers went a little over the top with it. You always find yourself jumping around trying to pick up clips because you are running out really fast. I found that to be tactically limiting and also a bit unrealistic. You can not keep enemies down with sustained fire. Combat does not get more intense just because you have to reload more often. I think that clip size and ammo carrying capacity should be increased. To maintain balance, ammo could be rarer to find (in specifically placed ammo crates for example. That way you would still be cautious about wasting ammo, but capable tp lay down a carpet of suppressive fire to cover the advance of your team if you want to.
PROJECT FIREWALKER
I know you can't complain about free stuff too much, but you judge purchasable DLC by the quality of it anyway. Firewalker is, in my opinion, the weakest part of the game right after scanning. I know that some people disliked the Mako in ME1 but I fail to see how the Hammerhead was considered an improvement. PF is basically a platform jumper where you constantly crash into some obstacles sticking out of the ground, because you are flying so low. Combat is even worse. You fire inaccurate heat seeking missles (out of a cannon???) and basically end up frantically bashing on the fire button in the hope of hitting something like in some old fashioned arcade shooter. Then there is the "mining" which adds another level of annoyance to it that really shouldn't be there. The Mako was fun to drive and fight in and I liked the missions that had some Mako elements to it, except for the horrible mountain climbing elements. The Hammerhead was a bad decision and all you get for it is a Prothean artefact (!!!) that does nothing but vibrate on your desk. It seems like PF was either rushed or simply poorly thought through. They should have used the time and dedication that went into PF in favor of improving other elements of the game.
SCANNING
I'm sure I'm not alone when I'm saying that "planet exploration" which can be more accurately called "scanning" is the most boring and anticlimactic part of ME2. All it comes down to is busy work. This isn't planet exploration in my book. It adds nothing beneficial to the game exrience. Sure, you can find the occasional N7 mission but these are few and far between and usually very short anyway. I prefered how planet exploration was handled in the first game. It wasn't perfect, but it was far better and more fun.
STORY
The story of ME2 was great...sadly it was also a bit short. It took you about three missions to find out what the collectors were up to. I think it would have been better if this aspect of the game would have been drawn out over several missions, where you had to fly all over the galaxy to collect bits and pieces until you finally could put the pieces of the puzzle together. Most of the missions you are doing really only relate to your squad members and have very little to do with the actual goal of human colony abductions. I'm not complaining about what is there, I just would have liked it to be more.
MISSIONS
I loved most of the missions. The only thing I can criticize is the fact that I would have liked them to be longer and offer more content. It would have been great, for example, if you would have been able to split your team up into strike teams more than just once in the final assault on the collector base. Also, the cut scenes were really good and I would like to see more of that outside of the endgame as well.
N7 MISSIONS
I'm glad they are there, but they seemed really rushed and somewhat out of context. A shame, because some of them had the potential for great atmosphere, like the abandoned space station or the wreck of the Estevanico. They really should have been fleshed out more and a bit more story context would have been very welcome. It probably would have been a good idea to realease them as a DLC pack (making for longer side quests with better developed storylines), allowing the developtment team to spend more time adding content on the main missions. Well, I would have bought it.
WEAPON ACCURACY
All in all I have nothing to complain about here, but there is one point I wanted to mention: I think that at least the soldier class should have had some accuracy increase as you level up your skills. This is mainly due to the fact that its biggest plus is the machine gun, which is horribly inaccurate. Without the accuracy upgrade this weapon is almost useless, which really is a shame, especially at higher difficulty when it is dangerous to pop your head out for more than two seconds. But even with the upgrade you need to crouch just to fire a short burst with acceptable accuracy...and you can't even crouch at will. you have to find low cover. Why wasn't the option added to crouch at will?
LEVEL CAPS
Now, for some reason Bioware LOVES level caps. I never quite understood why, especially in a game where your enemies level with you. I think you should be able to level up to the point where you can max out all your available abilities. This has not to be achieved in one playthrough. It is totally okay to take more than one, giving you a feeling of advancement and reward as you take the same character for a second or third playthrough. Using your powers are one of the major fun aspect of the game, so why not allow the player to use them all at their maximum potency? You have to do some picking and choosing as you level up anyway and it does suck when you find yourself or your team mates stuck with a handful of skillpoints left over that are not enough to improve anything and as such just "hang in the air" for the rest of the game.
SQUAD MEMBER COMMANDS
I was a little dissapointed when I saw how limited your tactical options were. I would have liked some additional commands like "covering fire," "hold position," or "duck for cover" rather then just being able to tell my squad to go there and there or use a power on a target.
ADDITIONAL IDEAS
I would really like to see vehicle and space combat playing a larger role in the sequal or possible future DLC add-ons. For example I think it would be great if you could aquire multiple vehicles and then use them all at once in an assault on a base where you would basically have to make the approach with vehicles and fight your way past the first line of defenses before you send your team on foot into the station or ship. I liked the way vehicle combat was resolved in ME1 and I'm sure the Bioware team can build up and improve on that. But most of all, I'd like to be able to send in more than just one squad at once rather then just picking 2 team members while the others sit idly on the ship.
Well, so much for my feedback. I hope it is not considered flaming since I really like the game and just tried to give constructive criticism for what I, as a fan, would like to see in further add-ons and ME3.
