And Eberrron was created by WotC in third edition, when the design paradigm had changed from "beating PCs into submission" to "lets offer cool alternatives that are tied to the world."Artificers were added for Eberron. Settings typically have new spells, equipment, kits (subclasses), ancestries, feats, etc. to enhance things. I allow splatbooks and third party products as long as they seem reasonable, both mechanically and thematically.
No, what I'm suggesting is things that are universal systems that improve characters, not reduce them. Stuff like action points in Eberron or extra feats in Dragonlance. 3e onwards has more-or-less added to PCs in different ways while 2e was primarily focused on reducing stuff. The sole exception I can think of was Dark Sun's free Wild Talent.As far as "why don't you create settings by adding new super-powerful options," well... because if there are new super-powerful options, no one's gonna take the standard stuff. I'm going to have to create an entirely new game's worth of super-powerful classes, ancestries, spells, monsters, etc. I'm creating a new system at that point.
