I agree with Xior and I think the term he want to use is COSMIC fantasy, a term I made up for this

You see, for me age of sigmar is following the route of Spelljammer or planescape of ramming the fantasy out of 11, unlike low or high fantasy were evertyhing is in a sort of "earth" place cosmic fantasy deal with enterely fantastic and damn weird places it and dosent pretend is any sort of realistic by canned the earth-like setting in the first place

that is why for me age of sigmar have to go higher, they are not a regular setting and cannot pretend they are, is not "this is just a typical village in a realm of metal" made them feel they BELONG to that, otherwise is a wasted of time.
