Topic says it all. Personally, I just use my favorites and don't ram anyone if I can avoid it. I know its GTA and all, but my thinking is that this isn't Twisted Metal or Burnout, its a race. If I have to ram you off the road to get a win, I didn't really beat you, I just took you out of the equation altogether and might as well be "racing" alone. Of course if someone rams me first then all bets are off if I see that player again. I also don't use custom cars, as I feel it gives an unfair advantage against those without custom cars.
What's your thought on this?
