Valve promises that they won't develop major exclusive titles for Steam OS, though other studios can independently decide to release solely on the upcoming Linux-based operating system.
Which means, basically, that Half-Life 3 won't be exclusive to the platform. If it ever releases at all that is.
“You won’t see an exclusive killer app for SteamOS from us. We’re not going to be doing that kind of thing," Valve's Greg Coomer told IGN.
“We believe that, in maybe five years from now, folks will find it a quite antiquated notion that you should assume that when you change devices or platforms, that you lose all of your other games and friends. We’re hoping to unify, to get Steam to be as platform and context agnostic as possible. You shouldn’t have to shed that every generation, or even slightly shed it.”
“It would be pretty silly” for developers “to limit their game to a certain platform," he concluded.
Good to know, since splitting the Steam client and SteamOS audiences is a surefire way to stir up some backlash.
Though both SteamOS and Valve's Steam Machines living room PCs are still months away from a full reveal (yet alone release), you can eyeball one here. Spoiler alert: it's a black box with vents in the top.
Somewhat off-topic: I've been recently thinking about whether Half-Life 3 will actually ever release. See, when you balance potential risk vs reward for Valve, you have to wonder whether the smart play would be to never release it at all. Valve's not exactly short of cash flow, after all, while the potential for disappointment and disillusionment has to be a worry. Just my own personal musings really - anyone want to engage on this slow news day?
