Summary: Obviously, first we need to talk about the ending. I didn't really mind it. People say it doesn't matter what you choose, because you get the same 3 choices for endings anyway, but Bioware themselves said before the release that no matter what, Shepard saves the galaxy. I view it less as "your decisions didn't matter" and more as "all your decisions were different means to the same end." I just can't get worked up over the ending like other people do.
Summary: Overall probably the toughest combat in the series, very rewarding to beat certain sections. However, they really cut down on the rpg elements of the game, resulting in less character conversation options and an overall lack of immersion. The fleet collection missions which i had hoped would give me a cooler ending still only showed human ships at this "final climactic battle for the galaxy" despite my "fleet" having every race in the galaxy in it.
Summary: Mass Effect was a great series, if you are here you probably want to finish the story and see what your decisions have influenced. And you should! But take it with a grain of salt. Instead of having richly involved conversations and interesting relationships, interactions, for the most part, have been reduced to on-screen text while you walk by people.
Summary: I loved ME and ME2 and eagerly awaited the finale. I was very disappointed in this game. It was so unimaginative and had overtones of just stealing from the competition. The facial and body animation is a throwback to poor attempts like in Deus Ex HR. Tight and unrealistic, certainly not up to the ME2 standards. The ending also was reminiscent of Deus Ex HR, which I liked for that game but seemed contrived for ME3. Like let's get this over with.
Summary: Haven't reached the end yet, but I watched the spoiler before buying. Enjoying it for the most part, I thought it was a little racist that the one Latino character is all full of himself and swears at you. It'd be nice to have vehicle portions like in the first 2 games, but I like that you can mod your guns again, this was there in the first, but not the second. Game play seems like a compromise of the best features between the first and second Mass Effects.
Summary: Great game, but knock 1 star off for bad ending and another for banning mods on PC version. Let's start with the good - graphics, voice acting, gameplay, etc. It's even more simplified from the ME2, which itself was simplified from ME1, but it isn't yet to the point of being dull. I certainly don't miss mining dozens of planets for elements. Combat is still quite satisfying and challenging enough, even if you import a power character from ME2.
Summary: Along with Diablo 3, this final entry in the Mass Effect series was one of my most anticipated games of the year. The game itself doesn't disappoint. I've played the game twice as both a Vanguard and an Engineer. There's nothing more fun than using a Vanguard's Biotic Charge. Or using a Cryo combo to shatter some hapless Cerberus troops. The mini-games have more of impact on the main quest this time, and they aren't as tedious as mining planets in Mass Effect 2.
