I have played on servers that have movecraft in space but trust me even though it was cool to play with, it is not really good in ccnet. The closest thing they could do is an event with Francis(he makes cool space-x in ccnet stuff) going into "space" but it wouldn't do anything beside be fun to go to or watch.

Not unless you add valuable items/resources to other planets (methane is pretty prevalent and other chemicals that could probably be great for SF). Not unless you add capture-able zones, like “The Moon Landing Siege Region” with daily energy-related rewards and vanilla xp. Not unless you make ship materials valuable, motivating space ship piracy and battles.

Theres plenty of potential value and would be a great post-game. I’ve been saying this for years

also, more custom movecraft info. There would be 5 types of space ships. there would be an orbiter(short range, can only exit atmosphere then needs to dock to larger ship) shuttle(short to mid range, can travel to the moon before refuling) Capital ship(Long range, needs to be built in space unless fitted with specific thrusters, used for space battles, similar to aircraft carriers in the sense that they can carry other vehicles, can travel from earth to saturn and can potentially leave the solar system if fuel capacity is big enough) the coloniser(highest range ship, similar to the capital ships but 3x as large, not as armed so would be better with an escort of capital ships, only use is for mass relocating of civilisations) and escape pods(low range, can only launch from larger ships, one weapon for defence, must dock to another ship) side notes, Fighters will work in space but only if they are airtight
