Xbox Live Indie Games have had a difficult time getting attention -- sometimes from Microsoft itself. But, that will (hopefully) change with a new developer-led initiative, called Indie Games Winter Uprising. Not unlike XBLA's Summer of Arcade and Game Feast series, this timed promo will highlight over a dozen "great games" on the service with "prices as low as 80 to 400 Microsoft Points."
The promo will last for exactly one week, during the first week of December. With games from Ska Studios and Radiangames participating, this should certainly entice newcomers to the Indie Games section of the Dashboard.
