Why in god's name are we trying to connect Ehrgiez of all things into the FF world? We might as well start work on Chocobo Mystery Dungeon and Chocobo Racing:rolleyes2 Hell lets not forget that Tobal no.2 has a Chocobo in it

Let's try to stay focus on the main FFs and worry about spin-offs later.

So how would one go about overcoming the "Magic" issue in the FF series, since it is most likely one of the greater inconsistencies in the series. VII (and to a possible extent X) have Materia but VI has espers, VIII and XII has your party drawing forth power from the world around, IV and IX gives the impression of "natural ability" while I, II, III, V, and once again XII has your party purchasing spells which gives the impression of latent ability that needs to be honed carefully through possible scrolls and written incantations.

Obvioulsy VI and VIII are going to cause the most problems as well as materia to some extent.
