Lets see…
-Everything related to Bethesda’s mod scene
-The entire Touhou doujin scene, even including sold games/music
-Sonic games which included fans being brought in for sonic mania
-Megaman and Street fighter have huge histories in modding. Pretty sure megaman has an entire fan-game for Zero’s orgin story
So…That gives us Bethesda, Sega, and Capcom at minimum for big players, and Touhou pretty much shows you aren’t going to lose your fucking IP over this.
No, Nintendo really does just do it more often than everyone else. You don’t gain that rep absolutely everywhere just on hearsay.
Bethesda is owned by Zenimax, and an officially licensed mod scene is completely different.
If you want to run the mods for Bethesda’s games, you need the retail software to do so.
I guarantee that if a group was creating a Morrowind remake that didn’t require owning some Bethesda core game that was being modded to achieve that, Zenimax’s lawyers would be quick to be on top of the issue.
It’s not like there’s not examples where Bethesda’s lawyers caused mods to be shut down where it involved redistribution of Bethesda game assets without needing to buy the game.
