Though Howard was reluctant to give many (well, any really) specifics, he did confirm that the studio has three large projects in the works – two "classically Bethesda" games and a new mobile game.
"We've got a good number of projects on the go," he said. "We're bigger now and we do want to be putting out more stuff. We have two larger projects that are more classically the scale of what we do, but even bigger. We overlap the projects so we're working on them at the same time, but they're staggered," he teased. "I can't talk a lot about them, but I can say that they're bigger than anything we've ever done. They're a bit different, but definitely in the wheelhouse that people are used to from us."
Howard was similarly cagey about the studio's new mobile game, although he did mention that he'd learned a lot from the experience of making Fallout Shelter. "It was a huge surprise to us," he said. "Particularly how successful it was. We've got – what – 75 million players now? The one takeaway was that the game is somewhat unique, so for the thing we're doing next we wanted to continue to do that. We need to not look too hard at what's working well for other people. The game we're doing is a very different style game, unique in the space. There isn't something else we're looking at for style."
