Really? I haven't read the book, but it looks more like 80s nostalgia stuff for adults in their 30s, 40s and 50s.
That's exactly what the book did.
It's about post apocolypitc world where a majority of things are done in VR (school classes, etc). VR currencies, real estate, etc all exist.
A billionaire leaves clues to a fortune where the quests involve all stuff from that time period - D&D, video games, etc.
It was a fun read, especially if the stuff he liked was the same stuff you liked.
