Portal 2 sales performed better on PC than on console, Valve's Gabe Newell has revealed.
With Valve owning popular PC platform Steam, you might have thought PC prominence was a foregone conclusion, but Newell has now said that platform sales are something the studio "can never predict."
"We just try to build good games and then we tend to be surprised," he explained to Gamasutra.
"Portal 2 did better on the PC than it did on the consoles; Left 4 Dead did better on the consoles than it did on the PC. So you know we don't try to guess, because we're not sure what value there is to guessing.
"We've never had a situation where we said, 'We really, really want to build something that is more popular for the console guys,' because usually we have a bunch of other higher priority problems we want to solve," he added.
"So we're glad that people want to play our games wherever they want to play."
Valve is, of course, usually very secretive about sales figures although Newell did confirm that Portal 2 had sold 3 million copies in June, without going into specifics.
