I slapped GNU GPL V3 in the meantime. For me video games are a medium of art which I believe would benefit from a different copyleft license. So far I'm not really going to enforce the GNU GPL v3. I still have to research some others when I'm not working on the game.
Only that they do not credit me with any derivatives that are made from it. If someone for instance decides to make a politically correct version of it for example, I want no association with it. Though I am worried about someone trying to claim it as their own and then they copyright the work, pretty much stealing it and locking everyone else out of it, if that makes sense.
Those are my concerns. Being credited for the original should be optional instead of a requirement so that rules out CC1.
I however do not like restrictions or unnecessary clauses or requirements, I do after all advocate for Copyleft and "Software freedom".

You can enforce that using a software license but that honestly is a trademark issue. The reason for credit to the original being enforced in all licenses but 0BSD because those licenses work via copyright which has to have a know author. 0BSD works via public domain. A different approach might be one which forces to highlight what changed. A really strong copyleftish license which does kinda that is the https://spdx.org/licenses/Parity-7.0.0.html license. If you got the trademark route apache license might be interesting.
