When Valve announced last week that it was building a Linux version of Steam, it said the focus on Linux was because "working with a single distribution is critical when you are experimenting."
On Wednesday, Valve head Gabe Newell admitted that another reason to focus on Linxus is because Windows 8 will be "a catastrophe for everyone in the PC space," according to VentureBeat.
At the Casual Connect video game conference in Seattle, Washington State, the Valve boss added that the Windows 8 fallout will drive top-tier PC makers away from the market.
Microsoft did not immediately respond to request for comment.
Newell is most concerned about what he perceives to be Microsoft's effort to control the Windows platform and limit access to competitors. With Linux, Newell said Valve is simply lining up alternatives.
Xbox Live will be part of Windows 8, which could hurt Valve's Steam platform.
Valve's first Linux game will be Left 4 Dead 2 (L4D2), with more to follow, possibly including the popular Portal 2.
Newell, a former Microsoft employee, argued that Linux is being held back by a lack of available games.
"I think that a lot of people – in their thinking about platforms – don't realise how critical games are as a consumer driver of purchases and usage," Newell told VentureBeat, citing Steam's Linux partnership as a "hedging strategy."
