I'm curious why the decision was made to not keep the missions linear as in PACG. On the surface, it seems like it will be much more challenging for the writers to tell the overarching story of the game this way. Doubly so if you can switch between chapters at any time.
Because some stories aren't linear. Don't worry, we've given ourselves more than 100 pages and 1400 cards to tell our story over the three sets. We'll be fine.
