If you want a similar minded game but a different thematic an genre, try Munchkin.
It's a really good card game with goofy things like a weapon called Swiss Halberd (yes, it's like a Swiss knife but pole arms), or the monster "Amazon" which do not attack female characters, or the "Whine at the GM", which gets you a free level.
If you have a small group of friends to play with, it's a blast.
