The story, as someone pointed out, is a sequel to the Journey to the West Novel. However, if you aren't familiar with it, the story in the game, you cannot make heads or tails of it. Furthermore, the Old Monkey who narrates the beginning is an unreliable narrator, making the game even more confusing. If you do know what the hell is going on, the story is quite interesting. Again though, it's seeped in Chinese culture, history, and religion, so for westerners, it just seems confusing and nonsensical.
