Hey there Steven, just to be clear about the license: if I bought the tileset, can I use it in an opensource game project? This should fall under the non-commercial type, and the assets will be distributed together with the opensource code .

So I understand that you just don't want people to resell your creation, is that it? Because putting it in an opensource game means people have direct access to the assets, like the FantasyHex tile set used here: https://github.com/yairm210/Unciv/tree/master/android/Images/TileSets/FantasyHex (I am in fact planning to use your tileset in Unciv just like this)
Of course, Unciv is also being distributed as a binary for download and play on desktop PC and Android phone.
Yes, reselling or making them available in the sense of "here are the hex tiles for your use so you don't have to pay for them" would be problematic. Being open source doesn't change much, because even if they are not open source, depending on the framework or engine, you could often still gather them from the content files anyways. I guess you don't have to dump the tiles' source files in there?
Really hoping here that people are honest enough to pay for the work I've put in if they want to use them for themselves in their hobby or commercial projects. :)
