I would probably like to mx and match spell lists from some of these games - in particular Call of Cthulu, Stormbringer, Classic Fantasy and RuneQuest - for my own game. They all operate on the same mechanical principles, except Demon Binding in Stormbringer (which is very powerful, and requires some though on how to balance its cost as a player option), but I wonder how the spell point to power level ratio might vary based on the game's assumptions of magic level and sorcery.
