Now in GTA IV, robbing a person it's impossible, unless you kill him.
It'd be good a "rob mod"....instead of killing people to take some money.....you have just to aim a weapon.
Then, there'd be in the upper right side of the screen "+ x$"...
If you aim a cop, two stars. If you aim a man with a gun obviously no money....if you rob a man at the ATM, more money....etc
Does it exist something like that?
