Flexpiel

Flexpiel is a fast, flexible, and genre neutral RPG based on FlexD6 which works well with FKR (Free Kriegsspiel Roleplay) style play.

What is FKR syle play? This blog post provides a good overview. In short: Play worlds, not rules. The referee doesn't need a lot of rules to run the game. They make rulings based on the fiction and what the characters are capable of. 

Very few rules are needed to facilitate that style of play. In the case of Flexpiel, the dice mechanic is built around the characters and situation. The referee starts the die pool by determining if the characters situation is normal, advantage, or disadvantage. Then the players may add additional dice to the pool based on the characters abilities and gear. The combination allows for a wide variety of success probabilities based on the situation and what the character is trying to do. It also allows for character growth through a combination of traits and gear.

The two screenshots provided here is really all you need to play the game. The PDF includes optional combat rules, tips for running the game, and play samples.

The "Referee Rolls Dice" version will not be maintained going forward, but I left it here because some may like to try it.
