For a Christmas episode, I'd like to nominate Planet Laika, a Japan-only PS1 game which recieved a fantranslation a few years back about a bunch of dog people (or rather regular humans who have dog heads because they traded their human faces to aliens in exchange for intergalactic peace) journeying to Mars on a fine Christmas day and losing their minds because Mars is alive and evil and actively trying to break them mentally. It's an adventure game with brief combat segments delivered through the medium of SPIRIT PONG.
For a regular episode I think it'd be cool to see one on Lobotomy Corporation. It's a brutally hard management sim centered around harvesting energy from what are essentially SCPs. While the game is ludicrously hard and unfair, I think Ross would get a kick out of the insane amount of corporate satire the game has.
I'd also like to nominate Dark Seed 2, an adventure game made in collaboration with H.R. Geiger with one of the most gloriously pathetic videogame protagonists I've ever seen, portals to alien dimensions, Twin Peaks inspirations, and uncanny fmv visuals. It gave me a similar vibe to Phantasmagoria 2 (which I know Ross loves) and you don't need to play Darkseed 1 to enjoy it (DS1 has its moments, but it has TONS of failstates and its very easy to softlock yourself, while DS2 still has a few spots where you can softlock yourself into a failstate its not nearly as bad as DS1.)
