Hello, all!
I wrote up a new arcane spellcasting class for use with the Pathfinder Roleplaying Game that comes with much of the same flavor as the wizard, but uses completely new rules for spell preparation. This class (the "mage") prepares spells as they are needed, rather than all at once, and is not limited to a certain number of spells per day or even on a system of spell points.
I made it into a Pathfinder Roleplaying Game Compatible Product, and it is 100% Open Game Content.
I put it up on RPGNow for $1.00. I hope you'll check it out.
