This is a new Kickstarter I think is pretty interesting for Ghetto Miniatures, a new range of 1970's New York Gangs and rules. As their blurb says: Battle it out on the means streets of the Big Apple.
I like this as it plays to a very Hollywood version of 70's street gangs (Warriors!), and so I find it more palatable than something emulating real world gang-fighting.
The campaign has 29 more days to run.
