Xbox's 12 Days of Deals promotion continues today with one of the best discounts yet, a 60% price cut on five Sonic games (plus an add-on), Major Nelson announced on Twitter. Check it out here.

For 320 points (about $4), you can pick up the Dreamcast original Sonic Adventure or the more recent Sonic the Hedgehog 4: Episode 1, with an additional 160 points netting you the DX upgrade for Adventure. 160 points will also get you any of the three Sega Genesis ports available on the Xbox Live Marketplace, namely Sonic 1, 2 and 3.

With only three days of deals left, we're hoping for some big ones. Keep an eye out, and let us know what you're hoping for in the comments or on Facebook or Twitter.
