I want to buy Outward, and I usually buy games from GOG and avoid supporting Steam if I can. However, I have read here in another thread that there can be problems with launching Nexus mods with the GOG version (the OP didn't clarify how and if they have solved their problem). .

Is it true? If so, can it be solved?

I don't want to buy the Steam version, but I will have to if the GOG one turns out to be incomplete.

If you get the game now you can mod is quite easily yourself using dnSpy.

The next build will no longer be moddable anyway (already the case for the beta release on Steam).

I have the same question.
Where did you end up buying it ?
