Some insight about what would make each planet unique:

• Luna: stone ore only, Vulcanus ash & rock tiles (excluding brown ones), craters, no humidity, solar like in space.
• Mars: iron/stone ore only, Fulgora/Desert tiles, Vulcanus cliff generation, solar inefficient due to sandstorms.
• Jupiter/Saturn/Neptune/Uranus, cannot land due to being gas planets

great

Do you want to participate in planning and design? Or just a player?

For now I don't know, I want to see how things evolve for factorio, but I have some experienc in modding.
Not helping would make a miss oportunity but I don't know how much would be needed.

Do you have a discord?

I really need creative ideas now

If you're looking for people to collaborate, you should create a discord and post a link.
