This book was TONS of fun, and should be for anybody who grew up in the 80s, especially if they were into sci-fi, fantasy, and gaming. So basically, me, which is why I liked it a lot. There are plenty of "regular" pop culture references as well, but the geeks and nerds of the 80s would probably appreciate it the most.
It's a kicky book about kids growing up in a not-so-pretty future, where everyone lives through a Matrix like setting (OASIS) to avoid the unpleasantness of a dystopian like future. The guy who created OASIS was a child of the 70s & 80s and creates the greatest adventure computer game ever to determine his new heir. The game is mostly about geek references that the creator of the system grew up with and the kids who have devoted their lives to studying every esoteric piece of his life (mostly 80s plus a little extra sci-fi/fantasy thrown in that didn't necessarily come from the decade, but are pretty staple for most geeks) and are racing to finish it first while doing that coming-of-age thing (throw in bonus "big evil corporation" while you're at it).
Lots of bonus cookies for Rush references. I deduct bonus cookies for a budding geek-romance that just felt tacked on and silly and some tremendously stupid things the main character did that did not seem to track with the story. Oh, and stacks of trailer homes. Really.
