One of my thoughts about the end... SERIOUS spoiler...
I don't feel like much was sacrificed for his victory, either... once the "end all Oasis" button was introduced, I was sure he was going to have to push it, and sacrifice this virtual world that he grew up in, loved, and just became king of, possibly to save his newfound friends. I don't know if the author is expecting to write a sequel, but for some reason that button going unpushed bugs me. Still, don't get me wrong, worth reading.
