Planet ability: "Acquire (Culture) for every ship landed in your galaxy" Does this count for any uncolonized planets that you have a ship landed on, or only for the home galaxy mat? Also, I assume ships in orbit over planets do not count, because they are not "landed". Am I correct?
My take on this question -> This only applies to ships that are on your Galaxy Mat. Normally they can only gain Energy from that location, but this planet's ability allows them to gain culture only from the ships on your Galaxy Mat when activated. Ships landed on planet surfaces or orbiting planets that would normally provide culture do not also harvest culture when this ability is activated.
I could only really see this being useful when you have all 4 ships available and at home on your Galaxy map. You get a move ship dice and can activate this to boost your culture quickly. Or, you have one leftover Colony Action dice after you just gained a couple planets. Your other ships would be home, so they could acquire culture to allow you to follow on the next person's turn.
