There's quite a lot of competitive #BoardGames at received either a co-operative expansion or standalone version, eg, #Carcassonne, #Labyrinth, #Concordia, #Orleans and #PortRoyal, to name a few. I wonder if there's a more comprehensive list...? π€
Also, I wonder if there's any examples that go the other way around, ie, co-operative #BoardGames that receive a competitive version? There's lots of "added adversary" expansions, eg, for #Pandemic or #LordOfTheRings, but I'm not aware of pure competition versions... π€
