Metadata settings are really hidden and people new to itch not know about it. Many of them don't know about it even when they have many games/assets uploaded...
I propose the following solutions:
- Add an opportunity to set metadata in creation time
- Add pop up menu (immediately after project creation) that encourages people to set metadata
- Add text about metadata in the end of the project creation page to notify creator that he/she should go there after uploading project
- Add proposal to set metadata inside emails you are sending to the creators when they published project but didn't change theme or added screenshots...
For those who are here accidentally and don't know where metadata is read it https://itch.io/t/2923877/setting-engine-metadata
P.S Most of CC licenses allow redistribution. If you doesn't know what means the license you point in metadata, so don't point it. I saw many times how someone sets in metadata CC0 or CCBY4 and say "no redistribution". It is essential part of them and if you say that you doesn't allow redistribution so it isn't longer CC0 or CCBY4 🤦‍♀️
