I also played this game when it was first released and, like everyone who has commented so far, I was also blown away. I used to work traveling, so I lost the game somewhere and never got to finish it, but it Looks like I'll get a chance to finish it now. The coolest memory I have about this game was how stoked I was to see the bad guys trying to avoid your shots by taking cover or ducking out of the way. I had never seen that in a game before.
There's no doubt I'll buy this game once I'm done with the other games I bought recently.
