@aaronpk I used to play Yugioh over chat client where everyone played their cards physically in real life and put in chat their plays, but that requires a considerable degree of trust that no one’s cheating. With friends, though, perfectly possible, especially if you’re playing caveman Yugioh (or synchro era or earlier in general really.)
But recently I thought about boardgames.
Just because of the current situation :
Boardgame makers – How about allowing buyers to scan the game and upload it to a tile server, so that we can tinker the meeples ourselves and play for example via leaflet.
Blackjack would work. Casinos use multiple decks. Granted they’re mixed up but it shouldn’t matter.
@aaronpk I don't have a list, but Goofspiel would work fine, so long as you could see both people's faces and what cards they played.
