The soundtrack...

I can't believe there isn't even a single thread about this, on the board with the best in-game soundtrack ever, fact... All the Grand Theft Auto games have had awesome soundtracks, and even been known for them to some extent, but Vice City raised the bar with this so highly I don't think it will beat again on soundtracks. What makes this game so great is the atmosphere, and the supremely-selected 80s songs set up 99% of that atmosphere. Not to mention, the soundtrack itself with its near perfect selection of power ballads, new wave, glam rock, stadium rock, hard rock, 80s pop, disco, soul, and old school hip hop and R&B amount to simply one of the best collections of music that I've seen in my entire life...
