1. Love the physics.
2. GFWL on top of RGSC and Steam? Screw you, Rockstar.
3. The online kinda sucks in my opinion. Maybe it's better modded?
4. It kept my save from when I pirated it. Yay!
5. The online hacking prevention appears either to suck or outright not work. A guy locked me in his car and told me to pay him real money to get out. And here's the kicker: he attempted to blackmail me in chat where everyone could see it, and no one did anything about it. I joined another server. Three minutes later, the hacker followed, and the host at least had the decency to try and kick him. It didn't go through somehow.
6. Nico Bellic is the biggest hypocrite on the face of the planet.
