Hi SpaceGod, or should I just call you God for short.
As you love the idea of the Starlifter that a given to have in your fleet.
Starfarer will be a great ship to make money early game. Or at least I think so, but as the game play not in who knows. As you have no out lay to get cargo. Other than the fuel and time to get where you can harvest gasses.
The Andromeda is a great ship.
But here the big one should you swop the Aquila for the Carrack. Are the willing to use NPC's when you cant get the people?. How much do you think you use it, what % of your play time exploring?
Carrack will be a great ship, not for me and I think some people on spectrum have over hyped it. But it will be a great ship. But it might be more limited in what jump point it can use, because of size. So that might mean take the long route to get where you want to be. But it have everything you need to explore in one ship, a one stop shop. Aquila will also be a great ship as well for exploring and could use shorter routes (smaller jump points). But will not have some of the stuff the Carrack has. But will need a smaller crew and be a lot cheaper to run.
Just thought of it so put it here. The Carrack will cost more in game, so buying it now will save you that grind later in game.
I think if you are going to use the Carrack a lot or you just really like the ship and have the money to spare, go for it. Wait until the ship is in game then use the CCU. If you find out you don't like it. You can just melt and get the Aquila back.
