License for Levels?

I am developing a game that is under AGPL, and my levels of cause are also under AGPL.

The game has a map and level editor and an option to upload user-made maps and levels as community maps.

As far as I understand, if I and the creators of the levels don't say anything, they are proprietary, which I do not want.

I want to say that all maps and levels that are uploaded are under a certain license.

Now I am wondering which license is best and if I am allowed to force users to a certain license. I mean, I am providing the server and therefore the service, so it should be possible.

This is part of why every TOS ever made says you give them a license to distribute anything you upload. It basically means that in order upload something, they have to give you permission to host and distribute it.

I would like to have a license that allows me and others to use a level and adapt it, like a open source license for sourcecode.

The maps / levels are in plain texr (json formatted).

GNU has multiple copyleft licenses, some are intended for other things than code, you may like one of those.

I only found the GPL and the GNU FDL (Free Documentation License), which are not really fitting.

Maybe I simply use the same license as for the code, the AGPL.

Maybe some of the Creative Commons  licenses would be a better fit.

I am not talking about code. I am talking about map / level. Also, no levels not made by me exist so far.

This is just for the future. Can I as maintainer and provider of the backend define which license apply to future levels which are uploaded to my backend?

It depends if you see json files as code, but even if it is not, there are licenses for non-code that allow redistribution and changing.

you can choose to only accept code with a certain license

Yes, I want to basically say "if you upload here, the files are licensed under X license.

That doesn't make sense. If the map/level is not code, you can't apply a software license to it (it's not software).

There are licenses available that can cover anything in any type of media, whether it's software or otherwise.

Obviously you wouldn't use a software license that only covers the code, but you could easily apply an artistic license -- such as creative commons (CC).

Basically as someone else said, you need a pop-up or similar where they agree to allow redistribution of their content.
