If you are open to fiction - I came across an entire genre called LitRPG which is combination of RPG-game style elements in the form of a book. It is mostly written by young gamers so the writing quality is pretty basic but various authors explore different gaming-related creative elements very well. Couple of books to start with in this genre are "Defiance of the fall" and "Dungeon Crawler Carl". The latter is even better as an audiobook vs regular book.
