“Costume Quest” is a Halloween themed role-playing game crafted by Double Fine Productions, the development studio headed by Tim Schafer that birthed gaming gems such as “Psychonauts” and “Brutal Legend.” This time around, Schafer was no longer at the helm, and Tasha Harris, former Pixar artist, took his place as lead developer. Was Harris able to pull off another clever creation for Double Fine, or does “Costume Quest” suffer from the curse of Schafer-itis?
