The GPL works for that.

The GPL works for that also.  You can claim a trademark on the name of
the product and the executables.  You can say "You have no license to
use these trademarks.  You must rename derivative works."  You can
tell people that their mods will only be included if they transfer the
copyright to you.  Doesn't need to go into the license.

An Open Source license cannot discriminate in this manner.
