Just curious, I would like a an employee of OOO to enlighten me on this issue.
My girlfriend really likes the art style of Spiral Knights, and she wishes to create sculptures of Knights in the likeness of other people's Knights, but does not wish to expend her resources and time without proper compensation, as any artist should. She is currently working on her own Knight, when it is completed, I will post images here.
Does OOO have any policies against selling custom works of art based on their intellectual property?
I think it's all down to discretion between the two parties. While it would seem in the ToS that trading art for CE is a no-no, I personally believe it's more of a gifting energy thing. I've paid a friend of mine some energy to do me a drawing, but I know it's good art, and I didn't mind paying for it. I am not aware of any policies that say "No u can not has arts based on our gaemz" But from what I've seen they do love to see fan art, check the SK twitter for example. I'm no employee, but from my point of view it's totally legit.
