A new Company of Heroes expansion is out, and it's doing well on both Direct2Drive's and Steam's sales charts. Probably will on the NPD ones, too, when they catch up.
But those ones take longer to put together, so until then, you'll have to look at a retail chart topped by...The Sims 2. And a World of Warcraft expansion. Sorry.
