Finally had the chance to play this game, gotta say, very unimpressive so far. Maybe it was all the 'OMG U2 IS THE BEST GAME EVERZ!!!11!1' in this forum that did it for me, but it's very much the same game as U1 with some graphics improvement, and a smoother story.
I also found it harder to suspend my disbelief. In U1, there were no scenes where I was thinking 'Wow, talk about being unrealistically lucky' and yet I must have thought that at least 15 times last night (I'm only on chapter 7 btw). It's just stupidly insane how he survives all this shit, he's superhuman. It really ruins the experience for me at times.
Don't get me wrong, I'm definitely enjoying it, but it seems like a very normal game experience so far, nothing earth-shattering like so many made it out to be.
@Dr.Grass, yeah I may be victim of the same thing. I kinda played them back-to-back as well (finished U1 about a month ago).
