Ernest Cline has written, not just a paean to early 80s video games, but a nostalgic trip back to the entire 80s geek culture. It pulls in details from earlier decades as well that were popular in the 80s (such as Monty Python) and is a celebration. Ready Player One is a book for people who grew up in that time or have an affection for that culture. The rest of the book is a mediocre mystery with not a lot of characterization, setting or plot. But if the subject matter is in your wheelhouse, then you’ll love it. So, let’s visit the future who wants to visit the past.
