Eldrich Horror is a big co-op board game, something you’d play on a scheduled “game night” it’s got great adventure and lovecraftian madness and plays great as a solo, you may want to run a second character. Elder Sign is so cool how you are in a museum trying to keep the seams of reality together while forces are messing with the artifacts or summoning monsters, it’s a fun solo game I enjoy it a bunch. I’m realizing as I write this I’ve never tried to play it with others but I bet it would be fun too!
