Hey. Demons & Derringers is currently the DriveThru deal of the day.
http://www.drivethrurpg.com/product/202194/Demons–Derringers-a-fantasy-noir
It’s a supernatural, 1920s noir setting/adventure starter I wrote, with a Tarantino or 90’s anime flair. It has been my go-to setting for pick up games for a long time now.
This booklet includes a bunch of NPCs, gangsters, and troubles, as well as several locations, macguffins, and a compendium class in case any of your PCs want a demonic gun.
Please check it out if that sounds like your kind of thing. The deal is only on for another half day.
