As the old Klingon proverb puts it, "today is a good day to buy things on Xbox Live Arcade". Well, I think that's how the proverb goes. My memory feels a bit scrambled, following the brain-shattering realisation that Klei Entertainment's Mark of the Ninja and Polytron's Fez are now available for less than the price of a Call of Duty map pack. Squee.
Assuming your exhilaration glands can take it, Rayman: Origins, Hell Yeah! and Trine 2 are also on offer along with the slightly less stellar but far from unappealing Rayman 3 HD and Sonic Adventures 2. If you don't buy at least one of these games, you're officially a Bad Person. Origins is a little harder to recommend than the others, perhaps, given that it's actually cheaper in a box. Sort out that Games on Demand pricing, Microsoft.
Tomorrow's episode of Christmas 2012 Xbox Live discounts is a Rockstar special. Stay tuned.
