If it works like older games I run on steam that have steam versions, yes you get access to workshop or at least I do on my Napoleon total war and shogun II physical copies.Title says it all. Thanks!
Indeed I have already pre ordered the game pass outside Steam. It seems I have to spend some more money to have the capability of releasing mods on Steam, which is and will continue to be the major hub for mods... I'll see how it works out at release.
It would be nice if some official staff came here with a clarification.
Can you run Steam Mods on standalone game versions?
