Rockstar has always taken inspiration for the Grand Theft Auto series from the world around us.
Grand Theft Auto: Vice City, presented dozens of nods to real world parallels of violence. The Haitian/Cuban gang war depicted in Vice City took inspiration from the cocaine cowboys that terrorized Miami in the early 80s.
Grand Theft Auto: San Andreas looked to the early 90s explosion of West Coast hip-hop in film and music for its inspiration. And throughout all of these titles the main protagonists were always some amalgamation of fictional incarnation and real world criminal. Like the games themselves, the protagonists were a blend of the real and the imagined.
