As others have mentioned, the book knows what it is, and doesn’t over reach its ability to make the silly entertaining. It’s a popcorn action movie of a book. As boatswain mentioned, the book is simi-satire, something that Ready Player One didn’t seem to understand when it ripped it off.
I want a Core One, but am holding out for the kit version, which I haven’t seen anything announcing a release date. I can’t really blame them, I’m guessing 75% or more of their printers are sold prebuilt, but I enjoy getting my hands dirty and knowing exactly how my printers work.
