I dont care what it costs. I care what you can do with it. How is the game loop supposed to look with it. What will be it's advantage over a station?
Anxthing else apart from being landable?
Will it have upkeep in form of metals?
Will we able to expand it?
Customize it?
Work for bonuses that fit our style of play?
How do we steer it?
Will we be able to crash it?
Will others be able to attack it?
Cost? Who cares. It will be expensive, then there will be a flood of snowflake tears on the forum, then every dad and his two sons will own one. So for me cost is tge least interesting aspect of all. By miles. Lightyears even.
Some of those questions are answered by Obsidian Ant in his latest youtube
I don't believe it can enter a planet or moon orbit or instance
I believe that the function of the carrier will be decided by the flavour of support ship that you purchase.
There will be a maintenance cost/effort
I don't think you can expand it, in terms of 'make it bigger'. Not sure what you mean there.
Whilst it is not clear if you would get bonuses for style of play, I have seen that you can choose the support ship for a particular occupation if you like. Piracy, exploration, search and rescue, bounty hunting and others.
Not sure at all about how or where you can manoeuvre the carrier and/or support ship. In real space, supercruise or wytch space. But I understand it can jump 500ly. But you need to synthesise special fuel.
I don't think you can crash it.
I understand it will invulnerable to attack.
Hope this helpe
