During a talk at Gamelab last week, Bethesda Game Studios' head honcho Todd Howard said, "Skyrim Switch has a big community that we haven't supported the way we'd like."
I followed this up with Todd Howard in an interview afterwards and asked what he meant. "They asked for mods," he replied, "they asked for Creation Club - 'When are we getting more stuff?'"
I asked what he was doing to rectify it. "Right now we're doing nothing," he said. "People, they're on other things. Our Switch group did Fallout Shelter ... and that's done really well. I'm surprised at how well it's done."
Then I asked: "Will you bring mods to Skyrim on Switch?"
"We are not actively doing that," he answered. "We would love to see it happen but it's not something we're actively doing."
