Will we have solar eclipses in the game?

I have no idea.

Well, if the planets are moving around on their rotations, I suppose it's technically possible.

I think logically, yeah, logically stating, if you think of all the things in play, then I don't see why not. Is it set up of like, oh, we're going to have a solar eclipse? No, but that's something that would, in a sense, naturally happen, I would imagine.
