Correct. Created maps are for personal use (not for sale). If you're making money or gaining some benefit from a map you created from my tiles, its against the use (the only exception to this being streaming or YouTube content). If you want to discuss a way to use the maps for commercial use, you can email me at zeshio.zworld@gmail.com. Options would be to include me as part of the royalty for the adventure or pay for a one time use to commercialize your map in a product. Thanks!
