Now that Chen's studio is no longer in an exclusive contract with Sony, its follow-up to last year's Journey could very well end up using a microtransactions-based business model, though that decision is still up in the air. Should the game go that way, though, Chen says it won't be like the majority of free-to-play games he's experienced, which he says encourage microtransactions by frustrating the player.
"I would rather see a game where you play to feel happier, and to make other people like you, and the make the people you care about happy," he explained. "That's something I've never seen in a [free-to-play] game."
Chen, who designs games based on an emotional aesthetic, says that he'll only go that route if microtransactions actually compliment the feeling he's trying to evoke in players.
