I haven’t had any issues that I couldn’t eventually patch, while I used to play skyrim I had 220+ mods plus few of my own mods. I am not saying that it’s easy enough but if you really know what you are doing and spent the time learning what a mod does how it does then you can work around the problematic part and modify those mods itself to work together.I have had multiple mods people said that couldn’t work together to work together. I understand the process is tedious and hours of manually patching is horrible but I don’t think we would get anything as close to this level of moddability for other engine. I have tried modding unreal but it’s just too terrible and hard to get into it and I can’t do anything meaningful beyond texture mods, maybe it’s my skill issue.

Funny that you mentioned fallout, I am now in the process of ironing out my new mod for fallout 3, the engine it uses game bryo is even more dated than the CE of skyrim and there are times that I wanted to smash my computer due to every single one of those time GECK crashed when I was in the middle of something important. But still considering Fallout 3 a game that was released in 2008 can still be modded easily than what’s a possible for a game from the time, I just love it.

Also as a person who spent hours dealing with fallout and Skyrim, I love their engine for what it is despite all the issues with it. And I hope that we get a new version of Creation Engine that can iron out the issue its having now, but Bethesda being Bethesda that’s probably gonna stay a dream lol, but anyway I have hope for my fellow modders.
