Or Dying Earth. However, I think the point was intended to be that outside the context of the books that initially inspired EGG's spell system or the novels directly stemming from his resultant game, there aren't a lot of iconic fictional magic users who use that model. Whether a a fatigue model is all that much more common (outside of tv shows and such, where it's easy to depict), I'm not sure (I'd say the grand majority just don't have magic be quite as overall convenient--slower to cast, more constrained to a single theme per caster, etc.; or just intended to be just-that-good which is fine because only the primary pro-/antagonists are the magic users and the supporting cast aren't being played by other players at the game-table).
