I'm A Player In My Own Novel!

Do you need me to explain any more than the title already did? Ughh, fine. Nathan(Also known as Nate, Nathaniel, Na aka Sodium) was an average writer, having endeavored and authored a few successful works in the fantasy sphere. One of his works, Tales Of The Seven, doesn't come up to this success, so he gives up on it halfway, only to then find that the greatest VR game studio wishes to create a game based on the world! As any sane person would, he accepted, and as development rolled around, he received an invitation to the game beta! Now, in front him laid the very world he created, and with the knowledge he was equipped with, he will become the greatest player, in his own novel!
