Sure, everybody likes going down into the dungeon and killing monsters for their stuff; that's a given. But what if that stuff had all sorts of clockwork gadgetry and steam-powered awesomeness attached to it? And what if the monsters were automatons and bad guys with flame throwers and flintlock pistols? And what if you had a fancy pocket watch? What then?
Well, then you'd have Munchkin Steampunk -- a new core set with all new monsters, treasures, and other goodies for you to use to backstab your buddies. And it's got brand new art from Phil Foglio!
