Stardock Central has dozens of games on it. Besides the Stardock ones, there's a lot of third party titles. I'm curious to know how many non-valve games the typical Steam user has. It has COD and Bioshock and such and Company of Heroes and the like so there's a lot more games on Steam to be sure, but I suspect the # of Steam advocates who have more than a handful of non-Valve games that they bought through Steam is not particularly high.
Anyway, Sins won't be on Steam before Half Life 2 is on Impulse.
