Both volumes are interconnected. Keen-eyed readers will notice:
The "Game Day" equivalent of Vol 2, but with more complex sequencing and weighted movements.
The limited edition of Volume 2 includes a "patient file" with replica admission forms, a torn page from Volume 1 annotated by an unknown patient, and a QR code that leads to a 10-minute audio drama set between the two volumes. That alone makes the set essential.
