Joe's played mysterium a few times with 4 or more players, he wasn't mad keen on it.Here's what we're playing that's new:
Sagrada: It's a sorta Yahtzee plus Tetris dice drafting game. The artwork is pretty neat. Seems to play really well with two players.
Just One: A co-op party game (for up to 8 people). Takes about 60 seconds to learn. Because we're children, we've sorta come up with some drinking rules for it that we'll probably test out tonight.
Mysterium: This we've only played with two people. It needs more. It's a 1 vs many-ish co-op game. Really, really neat artwork. Seems like it will be a TON of fun with at least 4 people.
