Operating system Windows 8 will be a "catastrophe" for PC game makers, according to Valve Software's boss.
Speaking at the Casual Connect game conference in Seattle, Gabe Newell said the next version of Windows could mean big changes to the PC market.
Many took his comment as a criticism of the changed user interface in Windows 8 as well as its built-in Windows Store.
The Windows Store could dent the success of Valve's own online market, Steam, through which players buy games.
