Was just having a little look around on the old internet with a view to spreading the word a bit more about rpgvienna when I came across aceofdice.com
It’s run by an Austrian fella called Alex and he’s written and published a rules-lite fantasy RPG and made it available for free on his site - the pdfs can be downloaded in German here aceofdice.com/?page_id=56
and the beginner guide in English(!) here - aceofdice.com/domains/rpg/?page_id=307
a quick look through the PDF shows that it’s of a very high production value and judging by the character sheet it’s very rules-lite indeed!
Something to think about if you’re looking for a quick one-shot in future.
