Valve did a sneaky, small-but-significant thing recently: it expanded its "Top Sellers" list on Steam to include one hundred games. The sales leaderboard doesn't tell us exactly how many copies a game sold, but it gives us a vague idea of how well certain games are doing on Steam in a given moment.
It's an inherently misleading metric—take that as a disclaimer. Still, as we sit in the shadow of some of 2012's biggest releases, I'd like to take a crack at gleaning what we can from this moment in time.
2K's having a great end of the year.
The $50 pre-sale of XCOM is outselling everything but Borderlands 2 on Steam. We might be able to chalk that up to fairly generous pre-purchase incentives (which could include a free copy of Civ 5 if enough people pre-buy it). It might be mild evidence that demos still work, too. Borderlands 2's high concurrent user count over the past few days (reaching 123,758 last weekend) is also evidence that 2K will win the weeks connecting September and October on Steam.
Digital pre-orders are a thing.
XCOM isn't the only thing-you-can-buy-but-can't-play-yet doing well. Joining the unreleased are Dishonored at #7, War of the Roses at #12, Football Manager 2013 at #17, Company of Heroes 2 at #29, and Hitman Absolution at #51. Even though there's no chance of a game going out of stock, Steam users don't seem to mind putting money down in advance, especially if they're rewarded with bonus content or a small discount for doing so.
Where are the MMOs? Oh, right.
Zero MMOs appear in today's top 100. I might consider that unsurprising—we wouldn't expect too many people to be picking up competitors while Guild Wars 2 and Pandaria are drawing the attention, and neither are available on Steam. Still, it's a little surprising not to see RIFT ($10) or EVE Online: Inferno ($20) popping up anywhere.
Call of Duty remains a PC fixture.
The sense that Call of Duty remains a fixture for PC gamers is supported by SteamGraph data. Some form of Call of Duty make up 10 whole entries of the Steam's top 100. Many of those are map packs, but the performance of Call of Duty: Black Ops - Mac Edition (#41) is interesting to me. It released yesterday, September 27, and it's outperforming stuff like Civ V: GOTY and Natural Selection 2. Modern Warfare 3 is 50% off until October 1, and it's sitting comfortably at #5.
DayZ continues to have a long tail.
I don't think Arma 2: Combined Operations (what you need to play DayZ) has left the top ten of Steam's Top Sellers since it caught on in May and June. It seems to be outperforming other games that released in May and June like Sins: Rebellion (#56), Max Payne 3 (#76), Civ 5: Gods & Kings (#20), and Spec Ops: The Line (unlisted).

Reiterating: We don't know what formula or data drives Steam's Top Sellers rankings. It's probably safest to consider them a representation of what games are selling well in one moment of time on Steam.
