Valve will not be developing its own exclusive 'killer apps' for the SteamOS.
In a statement to IGN, Valve's Greg Coomer said the Half-Life developer was not interested in creating content only available for its upcoming Steam Machines.
Coomer said it was an "antiquated notion" that consumers should lose all of their games and online friends between each new generation, with Valve ensuring Steam is as platform and content-agnostic as possible.
Valve's Anna Sweet also added the company was actively encouraging other third-party developers and publishers to release games across as many platforms as possible.
She explained the idea of an exclusive killer app on the SteamOS was against Valve's philosophy of openness.
"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," said Sweet.
"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.”
This week Valve revealed a first glimpse at the hardware for its upcoming Steam Machines. A full unveiling to the public is expected at the Consumer Electronics Show in Las Vegas next year.
