From TheGamer: “We recently got the chance to chat with Ghost Ship CEO Søren Lundgaard about Deep Rock Galactic, and you can check out our ‘making of’ article at that link. While we were chatting, though, we also touched on the possibility of the dwarven co-op shooter coming to other platforms. So, does Ghost Ship have any plans of bringing Deep Rock Galactic to Nintendo Switch?
Sadly, no,” Lundgaard said. “We talked to Nintendo a few times and we cried about the lack of memory. Thats the main problem – were using a lot of memory when were creating procedural caves, the destructible terrain, and such. We would need to branch it out and create a limited version that could work on Switch, but then we would have trouble updating both of those branches.”
