Even when there is nothing to do, there is so much you can do. Today in about two hours of game play on a friend's save I got a lapdance, watched a short movie, tried to hijack an airplane, played tennis, slayed a group of Baller gang members, and got gunned down by police choppers about 20 times. I also completed two small missions that didn't really advance the story, and did a lot of off-roading. It was simply fantastic. The humor in the game is top-notch. The map is astounding. I can't say enough good things about it.
