Played a bunch of games of Mysterium today with various folks who were visiting us for Thanksgiving. Man that game is a lot of fun. I know the English version in particular has a bit of a backlash for being a bit fiddly on the rules for a party game, but I didn't have that issue at all and played with a ton of non-gamers. Basically you just explain the first part, and then vaguely the last part and why it's good to get points and everyone just sort of gets it. Wish they had an expansion though that doubled the available cards as even in our four games we definitely got a fair amount of repeats.
