Its a tableau building game (race for the galaxy, terraforming mars, villainous, dungeon mayhem, fluxx, etc).
Play card, do what card says, redraw your card Once all players have played a turn its a "new age" which may or may not be a catastrophe (you figure out by drawing from a deck of ages) Once three catastrophes happen its the end of the game and you tally your points (written on cards). The company that makes the game has a 10 minute "how to play" video that you can look up.
Really fun and easy to play, and its inexpensive too!
