My idea of JA would be a shooter using exactly the same engine, but with more customisation and a story mode that would actually make you feel like you really are an apprentice. The premise of being able to customise your own character and choose the missions you wanted to undertake was rather misleading considering that the game is basically a totally linear and simplistic succession of levels.
No d20 rules that dictate how combat should go, no extensive dialogues, no companions to travel with you. Just *something* to make the whole experience more believable. Heck, a simple "home base" map (temple) instead of the menu-like mission selection would have been neat.
