Who knows this game? I've installed GTA5 and tried to run it, but it starts with the story line and probably goes from one scenario to another. Is there a sandbox mode where you can just drive cars? I even bought a book about the game but it's no help. Also interested in the "Real Life" set of mods, for which there's a ton of Youtube videos, but I can't even find these mods let alone install and use them. Seems to be a black art.
