@tufo so this post is 2 months old, but diplomacy is a board game from the 50s thats super fun & still being played online today! its a war game where everyone controls a different country (usually during WW1), & there's a TON of social coordination, social deception, betrayal, & alliance-building.
this event has already passed. currently there are two play-by-mail style games going on on fedi, but they're both taking a long time to conclude. if you're interested in giving this game a try, let me know & i will ping you next time a new game is opening up. we're always ready for new players ^^
