I have never had a more urgent craving to have been born growing up in the 80's rather than the 90s. I know it was a pretty cool era, but the insurmountable amount of references and basis of the book leaves me feeling very much left out (but in a good way, 'cos I still totally understood what was going on). 
 Right, I shall start with the bad things, okay? But considering the overwhelming amount of things that could have gone wrong, I've got very little to pick up on. But before that, let me just put out there, I nailed a Star Wars quote they had in here. AND I gave myself a high-five. Okay I didn't high five myself, but that would've been pretty sick, and at least in the spirit of things. 
 1. Infodumping was taken to some pretty extreme levels in this book. Interestingly, I would say that it didn't detract much from the book as a whole, as the information was all relevant, interesting and helped to set the scene. I can't see any other way it could've been done without adding a whole lot of unnecessary pages to the book, but occassionally I would just have to hold in a sigh, especially if it was repeated info. 
 2. Plot holes. Now in a genre that's based on VR/virtual reality, it's bound to be an issue. Let's not kid ourselves, there is no way an author is ever going to get it perfect, short of creating the bloody things for real and if they did that then they wouldn't write a fiction book about it (probably). Anyway. The complicated nature of the plot explains the info-dumping, but I did find a few things about the whole system that I couldn't help getting stuck on. (view spoiler)[ Like how does OASIS credit just immediately be used to substitute normal money? How are gloves supposed to help you walk in the OASIS? If you can make an RV solar power charged, then why isn't everyone driving around? (hide spoiler)] 
 But, honestly, those 2 are the only real things I took issue with in the book. I was really chuffed with READY PLAYER ONE. I expected it to be some SWORD ART ONLINE spin-off, like an English version of the Light Novels, but it was so much more complex and well thought out. I'm just going to write the top 3 things I loved about the book. 
 1. The 80's / 70's pop culture references. Yeah, I didn't understand most of them, the only ones I really got were some of the music, anime and games references, but even that made me feel like I'd accomplished something in the competitive game setting. Lame, I know. But I think the whole reliance on them eras really gave the book something special, and definitely something that sets it apart from the genre. Like I said, it really made me want to know more about what I missed out on (though I insist Pokemon and Rayman can rival anything you can throw at us) ahaha. 
 2. The whole geeky angle. This wasn't even limited to the games. Again it was the whole shebang of literature and film that made the book so god damn rich. But the plot being driven by the game really did make it so entertaining to read. 
 3. The game itself. Jeez. I give you a million applauds to be able to thread so consistently a world of that magnitude. The games within games thing you had going on there Cline; Brilliant. Even though the decades of gaming history were there to inspire you and to be used, they were woven beautifully into the story and it seemed effortless. 
 Basically I really was gripped by this book. I didn't know what to expect from it when I picked it up, but I am so glad I bought it. Once again, the UK cover kicks ass, that and the intriguing name was enough to catch my eye.
