Cyberpunk 2077

Both examples you gave are either early access or have lots of content updates still in the works. Skyrim modding broke like crazy when the DLC's released. Then they got fixed in time, Skyrim wasn't updated in years and it's been stable.

Then Skyrim SE released and that split the modding community again and the effects of that are still around today. Mostly not an issue anymore thankfully, but there was a period of time where you had to pick which version for which mods. Back to stable again.

Cyberpunk, Bannerlord, Blade and Sorcery - each update breaks all their mods until the modders fix them. That's just the nature of games that are being worked on after release.

Each Bannerlord update breaks mods. It's going to keep happening. Either the game is better off for it or devs use it as a crutch and is slows it down. Bannerlord seems like it's a bit crutched, but still moving along. It's interesting seeing what mods slowly make their way into base game.

Each B&S update breaks mods, but for the most part it's just minor json changes that need to be made. Devs aren't using modders as a crutch and the community is better for it.

Each 2077 update has broken mods, but I don't think any of the major ones that change the game have been severely affected by it. The most annoying part is, like with Bannerlord, once you finally get your mods playing nice there's a pushed update lol.

Personally I don't see why modders would pack up after P.L. when the patch dust settles. The game is done, they finally can be free of restraint and go as wild as they want without having to worry about more changes and patches mucking everything up. I'm not sure if these modders really care that the assets wont be useable for a 2077 Two because it's not the same game? Like, I don't think Fallout and Skyrim modders lamented the addition of other games.

If anything, having an incomplete game has been what has harmed the mod scene the most. Many modders I enjoy get a version out, update it once and ghost.

If games actually released in a finished state, that would be totally fine. They are not, and now mods get lost.
