A friend and myself here at work saw a few very short gameplay videos (whilst they're still there). We're both extremely excited about this game and couldn't stop ourselves from sneaking a peak. Even though the video quality is crappy as all heck, you can see that this game's graphics are mind blowing. The detail is astonishing. The way the characters walk and move looks ultra realistic which just immerses you into the game world.
I want to look forward to playing this game, but I don't own a console, and will only see gameplay when my brother plays it.
So I won't get the full experience until I get a console or when it eventually comes to PC, goodness willing.
I saw the gameplay vid this morning and the only part that looked cool/different was the driving segment. Everything else looked like it could have been in GTA IV.
