Ready Player One by Ernest Cline

Provided that you participated in 80's youth culture, this book makes you relive a bit of that as its protagonist works his way through puzzles steeped in video game nerd history in a bid to prevent an evil megacorp from ruining his favorite all-encompassing game.

This book has so many 80's references to video games, TV, movies, and music it's bound to jostle some memories loose. Oddly enough, it leaves out food and books not sold by TSR. There's no TAB, no Priazzo, no Stephen King -- were it not for the books, it would have seemed like Cline was writing on spec to generate Amazon sales.
