Valve games sold on Origin

Some might fight it very odd that various Valve games are appearing on Electronic Arts’ Origin service. Since Electronic Arts has pulled games like Dragon Age II from Steam because of conflicting policies on downloadable content, why in the world would Valve games appear on Origin?

Well, it’s not as strange as you might think. The only Valve games being sold on Origin are titles Electronic Arts published in retail, such as Left 4 Dead and Counter-Strike: Source. Also, all of those titles require the gamer to install Steam, so Valve would understandably be quite okay with the games being sold on Origin.
