I got GTA 4 back in April when it came out. I got the collectors edition which came with a music cd, a safety deposit box, a duffel bag and an art concept book. The game itself is awesome!!!!! The control scheme is very different from the past ones. In GTA 4, each vehicle has its own unique suspension. It takes some time to get used to the new suspension system, but once you do driving the cars is extremely fun. The overall scale of the game is ginormous!!!! Yes, I know that is not a word but I am going to use it because it is very apt. Anyway, I have enjoyed driving off the various jumps that I find.
I find that driving at extremely high speeds can only be properly done with no traffic on the roads. However, it is equally as fun to go really fast and then crash into a car and watch the car either flip and get really damaged or watch my character fly through the front window. I have yet to see anyone fly through the window of their car and then through the window of another car. That would be sooooo awesome!!!!!!!!!
