A Double Fine Production generally means quality and something a little quirky. That is definitely the case with their new XBLA / PSN cutesy role-playing title “Costume Quest. In Costume Quest you play the role of a twin brother or sister (your choice, thank you Double Fine for NOT assuming the players gender) on Halloween night. You go out together and your sibling is kidnapped, it is of course up to you to get them back. So goes the story in Costume Quest.
