It's a case of three different charts, two different weeks and three different games at the top, with WoW, Left 4 Dead and Tales of Valor all duking it out atop the PC charts.
Yes, with the Christmas season and recent run of AAA "proper" games well and truly over, things are back to normal on the NPD charts, which are yet again dominated by Blizzard and Maxis titles.
The Steam charts are just as predictable, though we will give a warm, hearty shout-out to Zeno Clash, which has done an amazing job and entered the charts in second spot.
