Ready Player One - Ernest Cline Labyrinth der Spiegel (Labyrinth der Spiegelungen #1) - Sergei Lukyanenko,  Сергей Лукьяненко,  Rainer Fritzsche

This book has definetely earned its place in the leading group of the category "What's the Hype". It consists of name dropping of eighties pop culture items and a more than sparse story constructed around them.
Yes, it was nice to "meet" all the movies, games and music from those days again, but that is all there is to it.
If you want to read a really imaginative and gripping story about a cyber easter egg hunt, I recommend "Labyrinth der Spiegel" by Sergej Lukianenko.

(Unfortunately there is no English edition available, but I have been told that an unofficial translation can be found online.)
