It's been about 6 months since I last played VC. I never managed to finish the game, but I did make it to 88% with only side missions and such left to do.
I love everything about the game. I liked GTA3 too. Awesome fucking style of games. I don't think I've ever liked any other kind of style as much as GTA.
My favorite mission... probably the one where I have to steal a tank. First time I ever attained and escaped a 6-star wanted rating!
Favorite vehicle... oh... Cheetah or Hotring Racer. The Comet rocked too.
Favorite weapon... hands down, the python. The rocket launcher takes a close second though.
