I'm obsessed with cardboard and plastic crack and would love to be able to talk about (and maybe play some on Tabletop Sim) with people who don't suck (especially Warhammer 40k, which doesn't have nearly enough leftists playing.) For card games I've been playing a lot of the Digimon TCG which is interesting and new enough to not have extreme nonsense like Yugioh or Magic.
If you're on :reddit-logo: there's still /r/sigmarxism, I don't spend much time in there myself so I can't really vouch for it tho
It's alright, lotta libs but the mods are pretty good.
