Last week's charts were dominated by two MMOs, Champions Online and Aion. This week? Looks like its the same story all over again.

Both MMO games continue to hold down the top two spots on both the Steam and Direct2Drive charts, ahead of usual suspects like Left 4 Dead, new/old kid on the block KOTOR and, surprisingly, Darkest Days. Pre sales also seem to be doing quite well and, we expect, will do better in the coming weeks and/or months, as more new games reach their release dates.
