Pandemic [0] is a fantastic co-op game with a relevant-to-the-times theme. If you like the base game, then consider Pandemic Legacy [1], which is probably the best board game I've ever played.
And if you just want some chaotic fun, Magic Maze [2] is a real-time, co-op game where the division of labor is split along actions (move up/down, move left/right) rather than across players. There's a very short time-limit, so games are quick but stressful, if you take them seriously, or hilarious, if you don't.
