The true GTA. So picture this!:
You're walking down the street, right, right? Someone walks up to you and starts talking. Someone runs up behind you with a baseball bat, hits you in the back of the head, and (depending how tough you've gotten sense the start) you fall down. You then have the misfortune to watch them mug you, and hop in an escape van. Whatever money taken is gone forever.
OR:
You drive a red light and a cop chases you, causing the cop to run the red light causing a truck to hit the cop. The cop could be dead or alive. (its random) If alive, the driver gets out his car, apologizes, calls an ambulance, but the cop arrest HIM instead.
Watchcha guis think? =D
EDIT: OHOH! Or, in your house decorating and a burglar breaks in and kidnaps your niece. OH! That could be a mission start. Track him down beat the crap out of him and get your niece back! Stuff like that
