It's like somebody took a s*** in my controller! I played this on the PS2, and it took a little getting used to (but I got it), but this? What happened? Trying to get in and out of the car sometimes takes a LONG Y button press, and... ugh. Failing a mission because of unresponsive controls = rage quit.
EDIT: Should mention this is the 360 download. I don't know how responsive the game is on the original XBox.
