Caves

[randomness5555]

Simple as, the surfaces of most planets are fairly boring. I don't know if it's possible, but if it is I would very much like to see a caves mod, perhaps with procedurally generated caves though that's optional. It would be a fun challenge for rovers and even more fun for VTOL pilots, or heck even for pilots with very manoeuvrable ordinary planes. Anyone think it's possible?

Dunno about caves, but I would like to see more canyons, ravines, precipices and other steep challenging surface elements. I think that this at least is possible.

Caves would be amazing....but probably not feasable
