During the course of what I imagine was a longer Skype interview on Pillars of Eternity, Eurogamer asked Fallout: New Vegas' project director Josh Sawyer what he wants to see in Fallout 4. Mods, slightly more challenging mechanics and choices that aren't black and white, it turns out:
"Fallout games are best when the choices are - and this applies to role-playing games in general, but Fallout is a more desperate world - more agonising. They feel more appropriate to the post-apocalyptic genre. So I hope that whatever twists and turns the story takes, it's more nuanced than a black-and-white choice."
[...]
"Also, you see that in the Road Warrior [Mad Max] films; Max, even when he wins, just goes on being a wanderer. There's that kind of bitter-sweet victory in the difficult choices that people make. Regardless of what the setting is, I would hope that that is a big part of the storytelling of it."
The same thing extends to the mechanics he'd like to see in Fallout 4.
"A lot of stuff I did in New Vegas was to try and make choices feel more impactful and meaningful and to challenge the player," he said. "Some people want to go through the wasteland like a tourist, which is fine - they don't really want it to be super-difficult. They want it to be interesting and engaging, and they want to see a lot of neat stuff and go through a cool story. And that's cool.
"Personally I like things to be a little more challenging," he added, "and there's a segment of players that also want [that]. I don't have any doubt in this."
