Gamasutra has published their XBLA sales analysis for December 2011. December was a slow month for XBLA games, but also very solid. The leader of the bunch was the re-release of Sonic CD, while Joe Danger wins the award for best review scores. Both Trine 2 and Scene it? had equally great reviews and sales. Voltron was the weakest of the month, having a strong first week, but ultimately had the lowest sales numbers and the lowest review scores by a large margin. All in all, the month was very steady with no huge successes or failures. You should check out every game on this list if you haven’t already.
