After reading the pdf walk through...I find it odd that the mage and bookworm choices are two separate paths. But almost all other mage stories, mages are book worms that read a lot to learn spells and other information that supports their desire to learn more, so they can have the advantage.
And having 3 separate paths (mage, warrior, bookworm), with each having their own different content outcomes...it becomes an even slower process for content to be released. And not sure about others, but I dislike replaying a title more than once to see all the content.
