Ooh, do you play Munchkin? I love that game
Sadly they only translate the first X parts to Dutch and now the compulsive part of me has to start buying them in English so it's possible to get a complete set -,-

I have Munchkin/ The Good The Bad and The Munchkin/ Munchkin Fu/ Super Munchkin/ Munchkin Impossible and Munchkin Quest with access to all the others (advantage of being the co-owner of a game shop).

But the game is named after old school tabletop roleplaying game players who would min-max their characters.
