Has anybody ever played in a setting where the disparity between magic and mundane is deliberate and system enforced? Eg. the PCs are all characters who have some measure of magical capability. The only system I'm aware of that reflects this Ars Magica, but I've seen a lot of works of fantasy where the magic users are simply substantively more powerful than those that lack those attributes, I'm curious if this is reflected in games, or what that might be like.
