The whole article is worth a look, but here's at least one good quote:

Heir: I think so. I think if we actually start making more games that make you think at the end of the day—that make you reflect at the end of the day and make you emote in different ways that just don't act as pure escapism. I think that's better for the medium. Not that it needs to go away—it absolutely does not. There is always a place for the escapist games. But you've seen games like Gone Home and Papers Please, games that have either messages or posit questions to the player to make them think deeper. Last year at GDC I gave a micro-talk on Papo y Yo, which is a game that literally made be ball my eyes out. I thought about it possibly every day for about a year. It made me reflect on my own life, my brother's suicide, how my family has been affected, and the way I was brought up— really a large number of things. That deeply touching emotion I thought made me a better person. I gravitate towards those types of games. I gravitate towards it a lot more than I do a sports game or racing game or a shooting game. There's nothing wrong with those games, it's just where I am personally in my life. It goes for all media. I'm done watching the giant tentacle Hollywood movies as well. I find myself watching more indie films and things with interesting reflective or emotive content. I think we need to be building content like that in our games, and I think it doesn't have to be exclusively about that. It can be in there and you discover it along the way and have these deeper thoughts. I think the BioShock series, especially BioShock one, had some amazing and interesting thoughts that at least created a large conversation even though it wasn't perfectly executed.
