Madness Level 9000 is a successful expansion, which expands Smash Up consistent and creative. The four new factions to play well and differ aureichend of the base game. Furthermore, they are wonderful with the political groups in the base game and balanced to each other. It's just annoying that the two cards "spook" the ghost fraction a misprint have (basic strength 4 instead of 3) - which rarely falls into the weight, but will disrupt a game purists inevitable. Who does not contest that, who gets with madness Level 9000 some wonderfully oblique fractions for more chaos and fun. PS: In addition, the printing errors of the two cards in the new expansion, "Science Fiction Double Feature" has been resolved and settled as replacement cards. So who is likely anyway to pick up more than one extension, can both get the same.
