Valve was able to launch an entirely new digital distribution platform by making Half-Life 2 exclusive to Steam. With SteamOS around the corner, gamers were curious: would the company do the same and make an exclusive game for their platform? The answer is "no."
Valve's Greg Comer confirmed: "you won't see an exclusive killer app for SteamOS from us. We're not going to be doing that kind of thing."
Sorry conspiracy theorists, it doesn't seem like Half-Life 3 will be a SteamOS-exclusive.
Third-party games are also unlikely to go exclusive to Valve's Linux-based OS. Anna Sweet told IGN: "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," she said. "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."
