Complete fan-made remake of New Vegas based on the Fallout 4 engine. To avoid legal disputes with Bethesda, the developers didn't use any existing assets and literally remade everything from scratch, including even voices.
Interesting that Zenimax/Bethesda's big beef is with the game assets itself. Though modding is a big part of Bethesda's culture, I wonder if the Microsoft takeover will fundamentally alter how Bethesda choose to exercise its IP rights in the future when such big modded projects are coming out.
Forgive my ignorance, but did anything substantive really come out of Creation Club or past attempts to monetize modding?
