Okay, so, who here has read it, and who here wants to?
This, by the way, is a fantasy comedy novel by the creator of the Zero Punctuation videos, Ben Croshaw, aka Yahtzee. It's about a student mage called Jim in a fantasy world who is killed, only to be brought back to life by a megalomaniacal necromancer. Problem is, there are strange things happening to the world. Death no longer happens properly, neither does aging, time has gone weird, and some adventurers have a strange syndrome that has them moving and talking mechanically, as well as gradually ceasing to move. And then, there are the strange angel-like beings whom Jim dubs the Deleters, capable of destroying anything in the world, and who have apparently recruited a pastor, Barry, to do the work of a god-like being called Si-Mon.
Now, the twist is pretty much spoiled on the backcover. Jim's world is actually an online RPG like World of Warcraft, currently undergoing beta testing, and the real Simon is a rather lazy but cunning and plagiarising programmer who decides to use the AIs that the development team created for his own gain.
Very Pratchettian in concept, but ultimately its own beast. Pratchett isn't as scatological, anyway.
Yami: Wanna play a game?
Ushio: What sort of game-
Yami: First one to die loses!
Yami: Look! the Queen of Spades!
Ushio: What does that do-
Yami: You lose!
Ushio: *falls* UAHHHHHHHHH!
