High/low fantasy and low/high magic are different things.
Runequest is low fantasy but high magic ( every PC casts spells).
DND has very predictable magic so is a terrible model for many TV shows.
Glorantha's magic is extremely predictable as well, and is usually of the low caliber, even powerful Rune/Divine magic is well below most D&D spells of even level 2-3 in effect. But this is only considering that Runequest = Glorantha, there were excellent settings for Runequest, for example Viiking or Land of Ninja where magic was entirely optional, and where Runequest's excellent low fantasy combat system could shine without any magic.
