I'm aiming for a PS4 in January and it'll be the GTA bundle.
Jsin, although yes, you play a bad guy. It's entirely possible to play the game without killing civilians and other players. There's a mode called 'passive' which turns you into a ghost. You can't harm other players and they can't harm you. All you need to do from there is play missions and races and such. That's the only real way to make money anyway.
Granted, there are some missions where you need to take out a bunch of Jurors but for the most part, you're killing scumbags.
If you don't like stealing cars, you can save up and buy your own. You honestly don't have to kill civilians and if you get into a police chase. You can either just let your character die or think "fuck it" and go out fighting.
I could play this game for months just using the racing part of it. Even rent it and try it with an open mind man.
