I think I'm the only person not looking forward to this at all.
I mean, I played through GTAIII and VC, where's the incentive to do it all again?
They also seem to have put in a bunch of pointless things like getting fat if you eat unhealthily, where's the incentive to eat the unhealthy food then? If that's all the effect it has, then what's the point of putting it in, ubless it's a token educational thing, which in a game like this is pretty lame.
The other thing is the focus on the hip-hop/rap gang culture which is a total turn-off for me
