I have a new LitRPG coming out next month.

LitRPG works right now because readers are aging up. Many readers now have grown up enjoying video games. Or if they didn't grow up with them they began playing them when they were adults.

Another great element about LitRPG is the formatting. Readers have the option to just enjoy the story without reading all the leveling game mechanics.

In many LitRPG books, including Hard Reset the formatting is clearly different allowing the reader the option to skip the details on what skills are being upgraded and just get back to the story.
