In 1987, the first commercial Norwegian-made RPG was published. It was written in English, and called “MEGA”. Mega was fun, rules-heavy and focused on realism. Due to some misadventures in business the game never reached a bigger market, and it’s fairly obscure even in Norway.
But apparently, in 2002, the authors wrote down a simplified set of rules – sort of a “Basic MEGA” system – and called it Amar. That system can be found on Geir Isene’s ::artweb pages, as a free download. It’s a labor of love, and it looks really nice!
