Really? I don't seem to recall pre-3E wizards kicking arse with swords as Gandalf does, or D&D wizards ever using spells in the same manner and type as Gandalf, or Aragorn wielding two weapons as a D&D ranger does, or any tales of King Arthur riding a divine steed and laying on hands to heal himself, or Robin Hood talking to animals and casting spells, or Friar Tuck invoking the wrath of God for a Flame Strike, or anything else like that. I don't see how a guy wielding a large sword and wearing armor, and possessed of heroic strength (though in Cloud's case unnatural), has any less in common with these 'icons' of D&D.
