In an interview with IGN, Valve’s Greg Comer confirmed that they will not release games exclusively for SteamOS. Comer stated, “you won’t see an exclusive killer app for SteamOS from us. We’re not going to be doing that kind of thing.” When Valve finally does make another game we won’t be forced into switching to a new system to play it. They seem to be going for a long term strategy that will not see new generations wiping out previous libraries.
This philosophy extends to third-party titles as well. “Whenever we talk to third-party partners, we encourage them to put their games in as many places as possible, including not on our platforms,” Valve’s Anna Sweet stated. “Because we think that customers are everywhere, and they want to put their games wherever customers are. That would go against our whole philosophy, to launch something that’s exclusive to SteamOS or Steam machines.”
There was an acknowledgement that there may be exclusives from small studios that can only afford to release on one platform but this is not an issue that they have any control over. Plus a successful game could than be ported over to other systems.
