"Saradomin, Zamorak, Guthix, Zaros, Armadyl, Bandos, the desert gods, elder gods, etc. None of them are actually "Gods" unless someone BELIEVES it."

It's an interesting point, really. Although, I believe contextually the definition of a god is someone who has achieved a certain level of power. But it's rather fuzzy, what with ascensions and such. Either way, I expect Jagex will release more information on the nature of godhood.
