I'm usually a fan of open source games but rarely do they manage to be actually great. People like giving recommendations like Super Tux Kart that haven't aged well and don't play well. What are some open source games that are legitimately good that I've missed?
It's an open world 2D spacefaring game, with a good core story and more being added by the surprisingly-active dev community.
Not without its flaws, but anyway I think it's a fantastic game in its own right. And it's both "finishable" and under continued development & expansion.
