I have all 3 versions, psp, ps2, and ps3 lol. PS2 version looks fine, if you havent seen the ps3 version (which is imo gorgeous fuk haters) then the ps3 version will still look great because the animation is extremely solid and the models look fine. I would recommend that if you get the ps2 version you immediately turn off the rumble function. It was quite a surprise winding up for a pitch the getting hit with RUMBLE!
I dunno what thats supposed to simulate but no thankz. Road to the Show mode is the best thing ever, its like an RPG for baseball fans.
