Another possible suggestion: Chaos Overlords. 1996 indie game. Turn-based, tons of 'gangs' for hire (each with specific stats and stuff), tons of equipment and other shit (control of the territory, racketeering, extorting money, snitching on your competitors, bribing dem cops, etc). Prepare for some tough bitchslapping, though.
Oh, and it also features some cool music. Enjoy.
