Standards are Carcassonne, King of Tokyo (although it's much better with more than a couple of players so better for non social distanced games), bit of Takenoko. A bloke I know has put out a game called Paupers Ladder which we're all enjoying. Sort of dungeon crawler style but lighter on strategy, heavier on luck - which works for us because the kids are in with a genuine shot at winning. https://www.boardgamegeek.com/boardgame/263938/paupers-ladder Hero Quest has also been dug out!
