Although the Xbox may have had a great December at retail, it's a little difficult finding a big success story in GamerBytes' recap of Xbox Live sales for the month. Trials HD is probably the closest, with more that 91,000 people picking up the game's "Big Pack" DLC. Sadly, new games fared much worse with Team 17's costly Alien Breed Evolution selling to only 9,001 players all month. 0 Day Attack on Earth moved just 3,336 units in its first two weeks on sale. It's not a pretty picture, but we're heartened by the fact that somewhere out there on this big blue ball, exactly 700 people are really into Polar Panic. That's nice, isn't it?
