>>40537695 (OP)A few which aren't mentioned often but are great:
>SanitariumOld adventure game. Bizarre, interesting, a bit "off" perhaps?
>NecrophosisThis one's new. Also adventure, short-ish, great mood and visuals. Not as deep as some claim, just lots of symbolism and references to ideas of reincarnation, godhood, rebirth.
>Cultist SimulatorSeems like a simple card game but the prose, descriptions, setting and mythology of the game very well mixes lovecraftian themes with more abstract ideas, without just going for typical horror spookiness.
