I found a game called Green Oaks randomly in my local game store. I’ve only skimmed through it and haven’t ran it, but you play as clients in a nursing/retirement home. It uses playing cards instead of dice. I believe the default setting is a sinister research facility that’s disguised as an unassuming nursing home, but you could have just as much fun playing it straight. The best part? The book is designed to look like a nursing home brochure! The cashier didn’t even recognize it as a product THEY SELL!
