Amazon has been dropping deals this week like it's trying to single-handedly stimulate the games industry. Today's "Prelude to Black Friday" offering from the online retailer features several special edition games at deep discounts, including Alan Wake: Limited Edition for a mere $30 (down from $80). That's the same price (a.k.a. 2400 Microsoft Points) the standard game will cost as a download when it arrives on Xbox Live's Games on Demand next Tuesday, November 23 (sans access to "The Signal" DLC, which is included in the LE).

Halo: Reach - Legendary Edition is also on sale, for a reasonable $75 (50-percent off), as the day's lightning deal, which expires at 5PM ET. Other all-day discounts on Amazon include the special edition bundles for Dead Rising 2, Modern Warfare 2 and Castlevania: Lords of Shadow. Head past the break to peruse our galleries of some of these limited editions ... if you haven't already clicked over to Amazon!
