Mass Effect 2. All the games had strong points, the combat for Mass Effect 1 felt freaking awful by comparison and the graphics are just unpleasant to look at. Hard military armor should not look like rubber. And Mass Effect 3...let's just say the ending and leave it at that. Also the dream sequences. They were kind of cool the first time, but after that they overstayed their welcome. My thoughts on the second time "Ohh, Ashley's voice and Mordin's voice? Damn, that's a nice touch, really shows you the Hell that Shepard is going through and how he isn't quite over the death's of this close and dear friends and WHY THE FUCK HASN'T HE GOTTEN OVER THAT LITTLE BRAT'S DEATH YET!? Also why is his jaw slightly open?" I would have liked it better if he was mounding the people he lost under his command and not the brat that he knew for all of five minutes. Seriously, I liked the kid at first, but that was before I knew I was going to have to put up with him all game.
Mass Effect 2. Had the biggest cast of squad mates, fun combat, and a ending that left me sitting on my couch smiling as the Normandy took off and the "No man left behind" achievement popped up on my screen, making me feel like I really did accomplish something epic.
