I was riding home from GameStorm in Portland with a game designer friend of mine, and he commented on something very interesting: that 3.5 and previous versions of D&D/D20 didn't really have a systematic way for players or GMs to create original spells in a rational, balanced way.
Of course, the alpha release to date didn't have anything in the Player's book at least similar to that (at least on a cursory reading). So I'm wondering whether this is something that could be pursued in future development of Pathfinder.
Man that is a great ideal be hard to make it able to make older spell prob easier to say use older spells as is new spell use this system though.
