GameTap now offers A Christmas Carol, this week's episode of American McGee's Grimm, the adventure game series based on the Grimm fairy tales (or in this case a Dickens novella). In the spirit of occasion, this episode is free through the end of the year so you can play it over Christmas. Here's word: "In this very special Christmas episode of American McGee's Grimm, our dark anti-hero and history revisionist corrupts Dickens' classic tale, A Christmas Carol. If you thought Ebenezer Scrooge was bad, you haven't met Grimm!"
