Possible unfree licenses for artwork

I’d still consider the game open source, even if the art is copyrighted.

Dwarf Fortress

Is there an open source version? It’s a great game (also try the steam edition if you check it out), but I thought it was closed-source.

osu! is an amazing rhythm game. Try osu!lazer, it’s the new client: https://osu.ppy.sh/home/download

I also like Pioneers and Endless Sky, both space sims.

This might not count, but both Lichess, a chess website, and OGS, a Go website are open source.

There is also Mindustry, but I haven’t played it.

I can recommend Sourcehut, it’s still free right now: sourcehut.org You will need to learn how to use Git with email, but that isn’t a bad skill to have anyway, so why not.

For anyone wanting to put their art under a free license, take a look at CC0

I find this question a little weird, because open source software (which includes the Fediverse) was already a very political movement from the beginning.

As for organizing, since there is no main authority or philosophy beyond make software open, it’s up to you and like-minded individuals to use the space as you seem fit.
