High-effort modding is really a thing of the past. With amount of effort required to mod a 3d game, there are only a few exceptions left, like alyx (desire to get noticed by valve) and skyrim (autism).
To still make mods, you basically have to be smart and dumb at the same time.
If you are willing to invest so much energy into a mod, you might as well just download unity and shit out a whole vr game, instead of working for free to make a game of some lazy dev better.
