I have been maintaining the Mythras character sheet and I'm preparing to add support for the M-Space setting/game. The issue is that M-Space though built on the Mythras engine is a game in its own right. If you buy the M-Space rulebook you get all the rules you need with no need of the Mythras core rule book. If I make a pull request which symlinks the html and css code in the M-Space folder to the Mythras sheet but have a unique sheet.json with M-Space specific defaults would that be okay/acceptable?
