(by way of Gamasutra
) has pointed out that in a recent interview discussing all things Dota 2 and Valve, Gabe Newell explained that Portal 2 was more successful on PC than console, while Left 4 Dead 2, surprisingly, was the reverse.
"We can never predict; I mean we just try to build good games and then we tend to be surprised," he told 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," he added.
