Hi, flarez26
The last version of the game and Storybook are separate titles.
So it's separate purchase with full amount of price.
And as i post in reply below - Storybook was created for our high tier subscribers (20$ and higher) - for thouse players who want give us more support... It's our way to say thanks for our high tier subs.
It have way more less content than original game - just to be clear, don't be dissapointed.
