2. Partying
Everybody likes to party, especially if it's a GTA party. Where there's nightclubs, there is also partying on the cold streets of San Andreas, Vice City and Liberty City. San Andreas introduced the ability to dance with a partner in a nightclub, and The Ballad of Gay Tony made it into a full blown side mission. Undoubtedly, this feature could return in an even bigger way in GTA V - that is, if it's allowed.
