........wow.........
The thing that I like most about GTA IV is how they drastically improved the driving. It is much more realistic but still fun as hell. The explosions in my opinion are pretty damn awesome, and when your car catches on fire as your driving and the fire is pouring out of where your rear tires are is awesome.
The story is very involved. I like the whole dating system alot as well. For the 360, they have a "Warm Coffee" achievement. Niko seems to be on top of his game with the ladies.
