Glad to hear. At the time, although I'd gotten some likes on the topic, all the actual discussion was arguments about how ships were just easier/better/cheaper.I'm interested.

One thing that I haven't mentioned yet is that, at least in my experience, you get a wider range of characters when the players aren't thinking about a ship. YMMV, but I find that once the players are decided on having a ship, they immediately start thinking of their characters in terms of the role they want on the ship and how best to make that happen. So scouts, navy, merchants, get heavily favored.
When there isn't a ship in the picture, I see a lot more agents, colonists, and other careers that don't immediately feed into ship jobs. Like, whenever the PCs have a ship, I can be reasonably certain that the soldier themed character (if there is one) is going to be a Marine. Whereas if the ship isn't a thing, I get a mix of army and marine characters.
It's rare, in my experience, that no one in the party can fly a shuttle or otherwise get a ship going around in system. But getting a full ship's crew tends to focus the attention of the players. The Mongoose "team package" helps with that, but I don't generally see players wanting to rely on that, so they tend to make characters from the shipboard careers.
