Another Electronic Arts game has been pulled from Steam, and EA says that Valve is once again to blame.

Last month, Crysis 2 disappeared from Steam, and the initial assumption was that EA had done it in order to secure an exclusive for the newly-rebranded EA Store, Origin. However, the game was still being sold elsewhere, and EA claimed the removal was not its doing, but Valve's. An explanation for Crysis 2's absence came later from EA's David DeMartini, who stated that Crysis 2 was removed because its DLC was available through Direct2Drive, but not Steam.

Alice: Madness Returns, another EA-published game, wasn't available on Steam at launch, but was added after a few days, prompting EA PR Director Amanda Taggard to say, "EA Partners and Spicy Horse Games appreciate Steam's decision to sell Alice: Madness Returns."

The latest EA game to be dropped from Steam is Dragon Age II. This week saw the release of its first big DLC pack, Legacy. Rather than sell it through Steam and other digital distribution services, it's available through BioWare's website and the game itself, which is what was believed to be the cause of its removal.

Addressing the situation in a statement sent to IGN, DeMartini blamed Steam's "restrictive terms of service which limit how developers interact with customers to sell downloadable content." According to him, "No other download service has adopted this practice. Consequently some of our games have been removed by Steam."

Battlefield 3, EA's biggest game of the year, has yet to appear on Steam. The exact reasoning for that remains unknown. The original Dragon Age and its expansion, meanwhile, are still available for sale on Steam, as are a number of other EA games.

DeMartini said of the Dragon Age removal, "We hope to work out an agreement to keep our games on Steam." But given that we still haven't seen Crysis 2 return to Steam after more than a month, it's unclear how much Valve is willing to budge, if at all.
