GTA is the only game i prefer to use a controller on console over my PC for.
Greatest soundtrack of any game in history = GTA Vice City
Greatest explorability and freedom = GTA San Andreas
Greatest graphics and realism = GTA IV
Greatest of all of that combined?? = GTA V I'm hoping.
As you can tell I'm a huge fan of this series. Ever since I picked up my first prostitute in GTA 3 in high school, I've loved this game lol. They all usually have really good story lines as well as replay value. San andreas was the most fun for the amount of content they crammed in, and with NO LOAD TIMES between cities. That was huge when it came out.
GTA V is a remake of San Andreas if I'm correct. Same cities/map, different storyline. I honestly can't wait for it to come out.
