If they go back to Liberty City (and I hope they don't for a while), please let it not be yet another rehash of modern urban NYC. That's played out. An interesting idea would be a parody of NYC circa 1978. To the rest of the world, it was the centre of the universe and where all the cool cats were. But peel back that thin veneer and it was a festering hellhole of crime and drugs. People getting murdered in the streets and no one cared. Cocaine usage and addiction is becoming common, which leads to a massive drug trade. Major homeless problem leaving many people with nothing to lose. A depiction of the first real downfall of American society following WW2, and the rise of major political corruption and the final nail in the coffin of the American dream. It's a time period GTA has yet to really explore, so could be interesting. And besides, who doesn't like 70s car chases with funk music in the background?
