I'd like to see a modern Vice City that follows up the events from IV. Sometime in 2010 would be great..
Since most of us were born in the late 80s - early 90s, we don't relate that much to time periods before 80s. The 70s in Driver 4 were like meh, the 30s in Mafia felt too old and the same for the 40s in Godfather. I'm basically saying that R* should stick to the 90s and later, otherwise would be too risky for a Grand Theft Auto game.
