It’s kind of new thinking in the games world. Todd Howard has said that if they’d anticipated Skyrim’s enduring popularity, they’d have released a lot more DLC for the game. Instead, they put out two DLC plus a home-builder addon and then moved everyone to Fallout 4. Which probably seemed like the best use of resources at the time.
Oh dear. I was planning on never installing Starfield Together. Now I’ll have to find some other multiplayer mod to completely ignore.
