Chez Cthulhu (reprint 2021)

From the publisher:

Prepare for an encounter with the most sanity-blasting entities in this or any dimension . . .  Your roommates.

Chez Cthulhu brings the horror of Lovecraft's Mythos right into your apartment . . . as if the leftovers from the Pizza with Absolutely Everything weren't bad enough. Work your job -- will you be a Morgue Janitor, a Sanitarium Attendant, or a Gravedigger? Buy things to give you Slack. A Straitjacket may be a good choice, but Friendly Tentacles can also be helpful. Oh, and Nookie, don't forget the Nookie. But avoid the Ectoplasmic Slime.

Chez Cthulhu combines the classic Chez Geek system with everyone's favorite Elder God and stirs in a new Madness mechanic, in a new stand-alone game designed by Steve Jackson and illustrated by John Kovalic.

Warning: Mixing Chez Cthulhu with Chez Geek can lead to bouts of giggling and excessive silliness. The game itself will play just fine, as long as your brain doesn't break when you use "cigarette" and "tentacle" interchangeably.
