Munchkin: Kill the monsters - Steal the treasure - Stab your buddy

Munchkin is an ingeniusly simple card game which, to be frank, is just too awesome for it's own good. Created by Steve Jackson Games, Munchkin now has 14 different versions of the card game alone, 2 versions of a board game and 2 actual RPGs. One of them is set in space.

The beginning of the original game is simple: you start as a level 1 human, with no class. As you go through the game, you gain levels, brutally murder monsters, steal their stuff, brutally cause your friends to be murdered (by monsters), steal their stuff, and just generally win.

In fact, the sense of humour of this game is great. In fact, it can basically be summed up in the card seen below, but not entirely summed up as that would leave no humour to be noticed later, which would be sad.

​

As a game, it has great replayability, and it also has a space version.
Also, zombies. Pirates. Cthulu. Axe cop. Yeah...

You can see/read more at their website, here.

If you want a sneak peek, they have a rigged demo, here.

 

Unfortunately, it's only available in physical copies, so buddies are required in real life before you can backstab them face to face. :/
