To answer your question from the Sword Art Online 14 thread (assuming you haven't heard this already), the Sword Art Online series is basically just a story about Kirito playing through various VRMMORPGs. Sword Art Online is merely the first game featured in the series, there's many more MMORPGs after this. Kind of like how the entire Harry Potter series isn't about the Philosopher's/Socereror's Stone even though the first book is named after it.
