My friends and I LOVE this game! It's so much fun. This game provides a good way for people in the group to get to know each other by encouraging spontaneous thought and general silliness.
I was one of the lucky few who got to play the prototype of MSU, and I was really impressed by it from the very beginning ^_^ It is a totally fun game, like the bastard lovechild of Apples to Apples and Mindtrap!
