The best thing about Grand Theft Auto: Vice City is not only the fact that when you're driving the various vehicles in the game you get to listen to the radio music (a feature which first surfaced in GTA III), but the fact that as the game takes place in 1986, the creators managed to license actual music from the 1980s to be played on the in-game radios.
Seriously, it fucking rocks. Even if you're not playing the game, per se, but just driving around in Vice City (a lovingly realized virtual environment by the way), just listening to the music is just so damn cool. We had the bad fashion back then, but our music ruled.
Rockstar Entertainment, who made the game, has the soundtrack on 7 CDs, each representing a "radio station". Yes, I am a sad git who bought the boxed set. I will take these CDs, and combine them with the rest of the 80s music I own, and rip them into one, giganormous monstrosity of an MP3/AAC playlist and travel back in time.
Except this time I won't get made fun of by the cooler kids.
