Munchkin is one of my favorite table-top RPGs. I think it's like a watered-down version of D&D. The rules are pretty straightforward once you get the hang of it, but there is still plenty of room for strategy within those simple rules.
Also the cards are HILARIOUS! The writing and names of cards are really sarcastic and the art is cute and also pretty funny too.
And there are tons of expansions. I've played Munchkin Cthulhu, Super Munchkin, Zombies and I have the original and Space Munchkins. All I can say is that they are all AWESOME. Cthulhu is one of my favorite expansions, but I don't have it yet.
Has anyone else played these?
