Come on. You guys know the first game is unpolished compared to the second. Story and characters are great - and very important for a game like this, but they still play second fiddle to the actual game play for me. I'm just not a fan of ME1's mechanics. The controls, UI, battlefield layout, AI, and other in-game elements are vastly inferior to the second game. I'm not hatin, I'm just saying that it isn't very captivating to me personally. It's a preference thing, but it's big enough to disengage me from the game. I never really feel like booting it up after trying several times and playing long enough to get into the missions. Never had that problem with ME2, which was brilliant start to finish.
Ah well, that's just my opinion. I won't say ME1 is a bad game, I can see that it does some things very well. Played PC version btw. No 360 right now.
