I don't like that you have to hold either L3 or R3 to run. I'm using "Alternate 2" because that's the best one in my opinion (of those choices, I'd like to map my own, though). I didn't fuck with L2 much, I only got to play it a little bit. Only took me about 15 minutes, I heard you can complete it in 7 minutes though. I think it looks great, don't really need to mention that. Gonna play through again real quick, then I'll probably have to go to bed. I'm getting this for my birthday, I pretty much knew that already, this just helps to hold me over a couple weeks. Gonna be hard to decide what to play when I have free time, this or Street Fighter IV.
edit: L2 is extremely useful (but will definitely take some getting used to), and the graphics are un-fucking-believeable.
I kept pressing L2 trying to run because I'm used to Resistance 2. Might sell it because after KZ2 comes out, I doubt I'll go back to playing Resistance 2.
