I am not sure if I can do anything with the mined resources but could not find a way to do so.
It feels a bit strange to rotate the camera with the right mouse button and use it for interaction too.

For the potential: I can imagine that this is your first project. WOW + KCD2 sounds quite ambitous and is virtually impossible to pull of. You probably seen it a lot but you should start with a smaller project.
I made the mistake and worked about one year on a passion project and reworked it three times from scratch because I saw that the whole project structure was off or the movement system would have to change to make it feeld good. Then I finally decided that I would have to learn a lot more to be able to make a game similar to Rimworld.
Not what I did at the end but if you want to make the game. I would recommend that you make the system in another project first. For example: Make Jam-Game about crafting with an inventory system. Then you can implement an even better system into your big project.
