Permission requirements for major tileset edits?

Well, I went ahead and just used the whole darn thing and included the attached screen in the credits.

I disagree with the last sentence. You're violating the spirit of copyleft. You could write something like 'If you want to use/edit custom "Nowhere" tileset, only Richard Dunn can grant you permission for that, I'm fine with it on my side'.

Copyleft?  I apologize, but I have never heard that term before. 
Could you perhaps elaborate on that please?

How about: Copyright, but right changed to left?

Its a wordplay. Some people use Copywrong too.

Copyleft open-source licenses read something like "everyone can use and modify as they wish, but their modified versions must stay copyleft, usable and modifiable by anyone". I think this approach is the best fit for default policy for content whose authors are unreachable.

Ooohhhhh. Gotcha. But, the reason I asked that no one else use the modified "nowhere" us because of the off chance that Dunn would ask me to take it off. If, for examole, 5 people use that tileset and I get told that Dunn doesn't want his tileset used like that, then 5 more people would have to do the same.

You have a valid point though.
