Yeah, then, when you're just about to finish that level, you realise, this is GTA, where you shoot people, run them over, carjack them and club them to death wiht blunt instruments. Not the sims, where you are condemned to a life of near pacifism. (Pacifism - look it up if you don't know what it means)
I know what pacifism means...
Besides, The Sims suck, as does pacifism. I think it would be great if Rockstar gave you a few Mini Games to play after you have squeezed every last drop out of IV. So, if you finally get bored of shooting people in the face, (Highly unlikely) you can stop.
