Hyper 5ystem

"Just write down a 5 and start to role"

Hyper 5ystem RPG is an experimental and minimal RPG system. The main trait of this system is that players don't need to do a character sheet before starting the game so you can start the session in pratically zero time. 

As general system another goal is to have a few general rules that can then be supplemented by more specific rules based on the setting and purpose (e.g., special rules for magic and prayers).

An add-on for fantasy sessions is under development, you can find it here.
