I have wanted to run a Sin City RPG for a long, long time and haven’t been able to find the right ruleset that sings to me for this. Can Index Card RPG do such a noir-inspired, hard-boiled setting? I think I saw there was a Vigilante City conversion to Index Card RPG and that might be the ticket for something like this. I own the Vigilante City OGL version.
Any opinions out there on my quest?
