Just thought of another film that would make an awesome game. Does anyone remember the film 'The Warriors' by Sol Yurick that was made into a film in 1979 and is now regarded as a cult classic.
The films about a powerful gang leader who is shot during a meeting between all of the city's gangs, the blame is pinned on a Brooklyn clan known as the Warriors and they end up facing a night of terror, as they try to return to Coney Island with an army of thugs hot on their trail.
The film looks a bit dated now as it is 25 years old but the concept for a successful game is still there.
