LIES! I've had this since March and I still love it

You get turf wars back once you beat the game.
The mini-gun spawns outside Toreno's ranch when you complete all his missions, and you can pick it up in the "Black Project" mission
Radio: flip to another station (1 above/below), flip back. Wait for it to turn red/orange, change it again, and back. Song skipped.
You're allowed anywhere, dammit. You even raid Area 51 ("Black Project" mission)!!
Los Santos sucks. Las Venturas is where it's at.
The easiest way to win turf wars is to get your Hydra (Harrier) or Rhyno (tank) and just rape everything
There are 6 C.R.A.S.H. missions, they are Tenpenny's, I think.
Sand-Niggers suck at life. Take their turf.
