Blood Bowl
The world of warhammer is one of the most ingenious and interesting out there. It got history and a different feeling from other shared worlds like forgotten realms or dragonlance. This world is grim/dark to the core. But not this one.This is Blood Bowl. It's set in the warhammer world but in a paralel world (kind of) where divergences are set in a game of American Football but with brutality that would put to the shame some world wars.
Here there are no rules, you've got a pig bladder and must put it in the other side of the field. That's it. Unfortunally there are really hungry dudes in the other side that will do anything (and I mean anything) to stop you.
In this tale we follow Dirk 'Dunk' Hoffnung rise from a swordsman to the quarterback of a team. Quite interesting reading. I really must read the following three books.
