John Carmack is known for developing some of the world’s most advanced PC graphics engines, but that doesn’t mean that he is blind to the merits of mobile games and their “pure” gameplay.
"I was really happy that when mobile came along with the more 'pure' games, they didn't have to be a $50 game that had man-centuries in them," he said. "You can have these small things that cost people a couple bucks."
"I don't have a lot of free time and I don't have 50 hours for Skyrim. That's not to take anything away from the massive titles, but it's great to have this broad spectrum of gaming," he added.
