GTA: British Columbia. It would work amazingly well because we have active gang and drug culture. Vancouver and Port Coquitlam have pot and recently gang killings and Maple Ridge/Pitt Meadows has racist rednecks and meth labs. Surrey has... Rednecks, less racist though. The island has rich culture and hicks. And all of BC has a rich heritage that could be unlocked as extras. Also, they could throw in my Grandma as an NPC you have to kill for a mission.
