Ready Player One by Ernest Cline

One of my favorite debut novels of 2011, it features gaming, typical teen awkwardness and issues over economic classes.

Everyone lives in virtual reality because reality is just to harsh to accept. The founder of OSASIS, the virtual universe, (think of Bill Gates) left his entire fortune and ownership of OSASIS to anyone who can solve easter eggs sprinkled throughout the virtual universe. Its set in 2044 and all the clues references 1980's games/history. Wade, the main character, is a poor, overweight kid living in a squalor development (called stacks) hoping to be the first to crack the first clue. I can't give anything else away but I LOVED it, I believe it has been optioned for a movie as of 2014.
