I think there is an issue with this content.
https://opengameart.org/content/16-bit-style-rts-rpg-world-asset-pack
The license on the OGA page is shown to be CC-BY, but the license inside the archive is different and is not free/libre.
Moreover the set is not complete and the user is requested to go on itch.io to buy the complete set for 5$
Here is below a part of the license:
The following applies to products marked for personal use <93>Personal Use Only<94>.
You MAY
-Use digital resources for personal projects.
-Use digital resources in educational materials.
-Use digital resources in an unlimited number of projects.You may NOT
-Resell, re-distribute, or share our digital resources.
-Claim copyrights to the resources.
-Use digital resources for commercial projects.
Thank you for bringing this up.
The proprietary license inside the package says it applies to products marked for personal use, yet none of the assets in the pack are marked as such, so I imagine this license doesn't apply to these assets. However you are correct that it is misleading and I will request the submitter remove or clarify that.
As for the set not being complete, that is actually ok so long as what is being previewed and described is what is actually in the download package.
In this case, everything in the package is as "advertised" by the description and preview images. As for charging $5 for the full package, I don't see anywhere on the submission where $5 is being mentioned, only on the submitter's itch.io page. Artists may sell art elsewhere even if they're giving it out for free here on OGA.
That is allowed so long as the full package is on a separate site and the incomplete package here on OGA is still in a usable form, which I believe it is; no watermarks, tileset is functional albeit limited in scope.
A usable version of the content is available here on OGA, so it's not really an issue. Again, the proprietary license is potentially confusing, so I will address that. Again, thank you for bringing this up. :)

Hi,
We can indeed consider the set complete if we consider extracting the tiles from the example image.
Inside the directory 128x128/ the files "tile_*.png" don't contain all the tiles needed to recreate the examples, in particular there is not all the side transitions between land and water: only 3 tiles: tile_002.png, tile_006.png and tile_010.png.
English is not my born language, but what I understand from the license is that the content is for "Personal Use Only". The archive contains a license file ("Policy.txt") that is not the CC-BY 3.0 advertised on the content page.
But I see that you disabled the download link, so we will see soon what they will do for this.
Thanks for taking care of the issue :)
For those reading this thread: the issue has been resolved :)
Thanks
