EA has confirmed that Dragon Age 2 DLC is the reason the game is no longer available on Steam.
Electronic Arts has confirmed that some of it's games have been removed from Steam because of disagreements over how DLC should be sold.
Speaking to Shacknews about the recent disappearance of Dragon Age 2 from the Steam store, EA's David DeMartini said that Valve's policies on the topic were 'restrictive'.
'At EA, we offer our games and content to all major download services including GameStop, Amazon, Direct2Drive and Steam,' said DeMartini.
'Unfortunately, Steam has adopted a set of restrictive terms of service which limit how developers interact with customers to sell downloadable content. No other download service has adopted this practice. Consequently, some of our games have been removed by Steam. We hope to work out an agreement to keep our games on Steam.'
EA hasn't explained exactly what Valve's terms of service dictate, while Valve has remained typically mute on the matter.
Earlier this year, EA announced a digital distribution platform of its own, dubbed Origin.
