Heretic of The Seventh Circle
Like DnD, I want to design a game that has an implied setting, or even references an explciti setting in the core rules, but that can be adapted to other worlds.
Yep, and that's the point. IMO you can't make a game that does what dnd does without an implied setting, nor would I ever want to design such a game.I disagree, to a point. Yes, mechanics enforce tropes, but some mechanics also enforce settings. For instance, when you said "allowing tying martial traditions to things like cardinal winds, elements, associated animals and mythic figures, constellations, etc. in a way that reinforces the lore of the world" that far more strongly suggests a specific type of setting than saying "fighters have limited spellcasting" and letting the DM or PC decide that it's tied to a wind or element or animal.
