Rockstar Had Planned a 'Spiritual Successor' to The Warriors

The Warriors is one of my all-time favorite games - I have a PS2 mostly to keep it, and Red Dead Revolver, fully playable whenever the nostalgia hits me. Though "The Warriors" had no cinematic sequel, Rockstar was plotting a followup anyway, one set in 1960s Britain at the height of the Mods-vs.-Rockers brawls.
