@NullTheFool For free assets I’d just use one of the Creative Commons licenses. They offer a lot of options.
For code, I guess the question is permissive or copyleft? For a less common permissive license, there’s Apache. It’s like MIT/BSD but requires a more clarity on modifications and patents. Or for kind of an oddball, there’s the Artistic License 2.0, which has broad relicensing compatibility with GPL or similar copyleft licenses but different requirements on distribution.
