Electronic Arts has said that Valve is responsible for the removal of Dragon Age II from its digital distribution service, Steam.

“Unfortunately, Steam has adopted a set of restrictive terms of service which limit how developers interact with customers to sell downloadable content,” said EA’s David DeMartini in a statement to Eurogamer. “No other download service has adopted this practice.”

Dragon Age II is the latest in a series of EA-published games to be removed from Steam. Other games deemed by Valve to be in violation of Steams terms of service include Alice: Madness Returns and Crysis 2.

EA recently opened its own digital distribution service, Origin, leading to speculation that these games represent casualties in a private feud.

Valve has not commented on the subject, but EA recently stated, “We want our products in all the places gamers go to download the best games and services. To that end, we offer games to EVERY major download service including … Steam.”

The removal of Dragon Age II coincides with the launch of the game's first downloadable content pack, Legacy.
