I played it like 6-8 years ago and all I remember is that it was on N64, Xbox, or PS2. It had a dude as the main character who was trying to figure who killed his Dad. There were pop machines you could get pop out of. It was somewhere in asia. There was a dude with dreadlocks who would dance on the streets and would say "Hey Mario" or something like that when he saw you. There was a bunch of martial arts. Thats all I know. Guess the game and I will reward you with something.
