Not really OSR related, but a fun game nonetheless! I made Murder of Crows a while back. A fast playing simple set-collection game where you spell the word MURDER before anyone else, first to do so reveals a unique murder story. Fun, quirky, a bit gothic in the Edward Gorey & Chas Adams style, easy to learn, and fast to play.
Atlas Games in conjunction with DriveThru cards has made an online custom card creator where you can make your own unique cards and put you or your friends pictures in as victims/perpetrators. Check it out if you're looking for a fun light game to add to your gaming night.
