As much as I love the other planets, this seems like a good idea to let people customise how they want to play. I will be working on delete-fulgora next and adding a compatability mod.
I will however draw the line at deleting shattered planet/solar system edge.
Reaching solar system edge itself is how you "beat" the game and I do not want to mess with that at all.
And I feel like the new endgame loop of getting as close to shattered planet as possible to get the most promethean fragments is core to space age.
So someone else will need to work on deleting those.
