Sorcery: replacing fatigue cost with something else?

Certainly other RPGs have played with a similar kind of concept, particularly "powered" oriented RPGs. Another approach is baking in some strict "cooldown periods" or uses per day (or both) on anything more complicated than a small bonus. The third is building in purchase of funky abilities into the character ("You get 200 points and one of these three powers) and severely restricting the number chosen.

But they're not GURPS :)
