This is totally blowing our minds. So Sony has an existing franchise called MediEvil, that is totally about a skeleton guy with swords and stuff. But the new PlayStation Move game it announced for PS3, Medieval Moves: Deadmund's Quest, which has the word "medieval" in the title and is totally about skeleton people, isn't a MediEvil spinoff.
It's a Sports Champions spinoff.
Emperor Morgrimm, the antagonist in this game, was a secret unlockable character in the Move minigame collection. The common thread is developer Zindagi Games, who is responsible for both games.
