That was actually a source of big controversy in the Magic community when the (overall very well received) Steixhaven card set was current, particularly from European and Latin American players: all the card tropes were American College stereotypes, and the card design team didn't actively notice thst until they started getting complaints. They just thought that the Amwrican College experience was normative. So that, at least, is the book following the source material. I haven't run the Adventure, bit I am intrigues by it's original structure and mechanics, and am curious how it would play out in practice.
