Games on Demand has added Red Dead Redemption, Prince of Persia: The Forgotten Sands and Narnia: Prince Caspian at prices one could kindly classify as "outrageous."
Red Dead Redemption is listed at its full boxed retail price of $60. We've confirmed with Rockstar that the digital copy is just the original game and doesn't include any of the DLC. Obviously, we recommend purchasing this through the marketplace like we recommend a rattlesnake bite to the groin. Prince of Persia: TFS and Caspian are priced at $30 apiece (way above their Amazon prices).
With all the deals we've seen leading up to Christmas, we can't in good conscience recommend any of these to you. If you have any interest in these titles, just wait and see what discounts will be available at retail after the holiday.
