Having generated caves could offer some good opportunities for new types of environments for planets. They could even have unique textures, decos, and even monsters. Maybe they could even have mini-ore deposits as well.
I know a lot of people like tunneling out areas and making underground bases, wouldn't it be cool to find an existing cave and build your base in there?
