Epic president Mike Capps has suggested dollar apps are putting meaningful pressure on full-priced retail games and could damage the next generation of console titles.
Capps told IndustryGamers that 99 cent apps pose more of a threat to $60 retail games than they do to premium apps like the studio's Infinity Blade.
"I'm more worried that you can get a really good 99 cent game that occupies you for hours and hours on end and how that impacts $60 SKUs," he said.
"I'm not as worried about how it impacts Infinity Blade - I think there will always be room for a premium SKU on a mobile platform. And I think as more buyers [enter the mobile market], there will be more people who are willing to spend a bit more for quality.
"But I do worry about what it means for the next generation of console games," he added. "Are people really going to want to spend $60 on a game? I mean, we're spending tens of millions of dollars making those games that they want to play... it's not a sustainable business model. I'm not sure how it all ends up."
Capps also revealed this week that People Can Fly developed shooter Bulletstorm "didn't make any money" despite its critical acclaim.
