Demigod is certainly not a typical RTS and was never intended to be. It has no kind of resource-gathering (not counting gold earned through kills) or base building. I would still consider this a strategy title, however, as you still are playing more from the perspective of third-person and your decisions affect the outcome of a battle. Taking into account the experience, armors, potions, accessories, etc, I would say this definitely has a bit of an RPG element with it.
