It's interesting that most of the games on there are games that are sold outside of Steam, neither The Sims nor any Blizzard game are available on Steam. MW2 was the hit of the year and despite the popularity of L4D and L4D2, neither show up on there.
Lets look at it this way, PC gaming revenue was $538 million for 2009, going by NPD. L4D2 sold 1.3 million PC copies in it's first two weeks, at an average price of $50 a pop, that's $65 million. It would be impossible for it not to be in the list.
It leaves me really wondering on how big of a chunk of the PC gaming market Steam has.
