Major Nelson announced on his blog today that the Xbox 360 Holiday sales will start with the incredible Bastion, which will be 50% off (600 points) today only. This'll be followed by a new deal every day until January 2, and if they're all this good, Microsoft's going to have a green Christmas (because of all the money, get it?).
Other deals are running for the next 12 days—notably, Insanely Twisted Shadow Planet, Oblivion, LEGO Star Wars: The Complete Saga, Renegade Ops, Plants vs. Zombies, Peggle, Peggle Nights, Bloodrayne Betrayal, After Burner Climax, Portal: Still Alive and L.A. Noire's Rockstar Pass are all 50% off. A host of Avatar items are in on it as well—check out Major Nelson's site for the full list, and keep track of him on Twitter for the daily announcements.
What games are you hoping to see discounted? Personally, we're rooting for ilomilo, but there were plenty of great XBLA titles this year. Let us know in the comments or on Facebook or Twitter.
