I know what you mean about it calling your name. I think that's a good plan because each book is very long, much longer than the average TellTale episode, so you'll be getting quite a bit of play time already. I actually plan on doing the same thing you are, playing from the beginning once all books are out. The way I play, I think I'm looking at a thirty to forty hour experience. Even if you play it on minimal path, I'm estimating it will be over twenty hours.

Just to warn you, book 2 does end on a cliffhanger if that's important to you. I don't mind because I'm used to it will TellTale, but it does make me want book 3 as soon as possible.

The developer said that book two depended on book one's choices we made during the game. Is there a way to delete book one to save room on the computer and keep the saved games? I imagine that's all I would need for book two, right?

Melia, don't uninstall Book One! You need to have all previous books installed in order to play the following books. I'm pretty sure you can delete old saves if you want to, though, with the exception of the very last save. Perhaps you should even keep the last two saves, just in case. The last save should contain information about all the choices you've made. Certain choices dramatically effect the outcome of certain story elements, so you definitely want to make sure you keep those.
