Well, if people come to D&D from material that is inspired by D&D then they will find what they're looking for.
But the most obvious thing about D&D - what the hell with the "cleric" class, ie armed and armoured healing priests? How is that generic?
You can find that sort of thing in most any game that has many different types of magic or classes in it, either explicitly or obliquely (i.e in Dark Souls). Sometimes you find a more clear split between the "Cleric/Priest" and the "Paladin" (or "Acolyte" and "Templar" if they're trying too hard to be unique), but that's all minutia. And it also gets back to the fact that DnD ultimately has a lot of stuff. The only thing DnD doesn't have, is strong limits on what is in it. You can find all the stuff from Game of Thrones or Lord of the Rings, in DnD, but you can't (usually) find just those things, they exist along a multitude of other fantasy... stuff.
