Auto aiming was to die for! I hope they include it in GTA IV. I kinda hated the graphics, that was before the PS3 and 360 were released. We'll see a large improvement in graphics on GTA IV.
I hated the dancing too, it's not GTA "Bust a Move" like UO said.
It increased your health in VC, there were a few food shops in VC, like the one in Vice Point Mall and that pizza place near the Malibu Club. In San Andreas, it was used to gain weight and make CJ be less hungry.
I think the Flatbed might be available in Portland in the beginning of the game, when you have to pick up Misty? Sorry if the names wrong, haven't played GTA3 in a few months. I'm not sure about the Bus, I think it's available in Staunton sometimes, in a 1 mile radius of Toni's apartment from LCS.
Raymond, wtf! Gerard is gay, you can't say he's straight. Jace & osiris., Rape is bad, sometimes I get an urge to fuck them but never rape. Gay people can do whatever they like, as long as they don't wake me up while I'm sleeping
Try downloading a trainer, spawn the two vehicles and put them in the garage in Portland. I think you can sometimes see the Flatbed and the Bus in Portland, but it is very rare.
