First of all, Munchkin Smash Up is a great set, don't let any Munchkin related prejudice stop you from buying it ;-)The things that were sufficent for me to get interested (and finally buying it and all expansions so far):
1. Richard Garfield game
2. Giant Monsters fighting theme
3. High player count (it's sooo hard to find something new for a 6+ player casual group every time they meet that's not a Werewolf or Party game).
