It's probably the best GTA game out there.
I remember trying two player once and you know how there's a kiss function?
Well me and my friend were on a bike (I chose a guy to play as), and we were going down hill. All of a sudden we were flying off the bike kissing each other. XD

There is always one thing I've found disturbing about the game though. Killing police officers. I know I sound weak, and I know its all fiction, I just always found it disturbing. But heck, I still enjoy the game.
