Phew, the Christmas celebration was over two days ago but unfortunately, I have a serious sickness since the beginning of this week so I wasn't able to do anything to celebrate. It was a shame for that to happen to me although many companies had planned something really big for that day.
Next stop will be the New Year's Eve and this on-going event will eventually last till December 31st with the different list of games so far for the Xbox 360. The second half of the event includes the Games on Demand and Xbox Live Arcade games but no DLC similar to the first half.
