So when I am talking about a no ship campaign, I am taking about a campaign where the characters do not have a ship they are associated with for any significant length of time. They might take a job on a ship here and there, if they have the relevant skills. But there's no particular expectation that they have Engineer, Astrogation, etc to actually meet the crew requirements. There was some sidebars about working passage above, but I consider things like "Aces & Eights", where they are hired as shipboard security to catch a swindler to be working passage, not just "my pilot got arrested, fly me to the next planet". Or being brought on as entertainers if the PCs have performance skills or other kinds of prestige that would make a liner journey sparkle.
In my campaigns, I like to emphasize that there is a lot of system ship traffic. I don't have ships jump from planet to planet with in the same star system unless it's going to take 2+ weeks to get there by in system ship. The lost cargo space and cost of fuel for jumping makes a big difference and my experience with shipping IRL is that businesses will almost always take a "order farther in advance to take a slow cheap ship" over "pay more for faster delivery". There are exceptions, but no one is going to pay for a jump ship to take their ore from belt to Earth if they can put it on a system ship.
That means that while there's no commercial shuttle to Rock #43, there are charters (with or without a pilot) that any moderately developed system would have so they can go to that rock when they need to. And, of course, there are both legit, gray market, and black market versions of said charters.
No ship campaigns probably do tend to have a smaller area of operation, though since I tend to run my sandbox games in a contained area like the Reft Islands, that's not a big change in my personal experience. But I really like to have recurring characters and locations in my games and that's easier without the temptation to "just go spinward, old man"
A lot of people think that mobility (aka a starship) is flexibility. I am not convinced on that score. Without your own ship, there is usually just extra steps involved in being able to do the ship type adventures even if your crew has the skills. Like how Magnum had to always go find his buddy T.C. when he needed a helicopter. Granted, you can also find a way to store your ship or whatever if you are going to go spend 2 months on a climb of Mount Anekthor looking for space yetis. But I think it is generally easier to hare off on whatever strikes your fancy without the burden of a mortgage (and especially without the burden of a subsidy). I can see that some groups might find it annoying to figure out how to get somewhere off the beaten track, but my group finds it a great way to use allies, contacts, and various social skills, generating a lot of RP opportunities that we'd often skip in just 'get in the ship and go'.
This might just be my players, but I find they are less obsessed with money when they don't have to worry about keeping
The Fat Pig of Aberdeen in good financial condition. The difference in scale between ship expenses and normal expenses is pretty substantial. So they are more willing to take a Cr5000 credit couple day job when they aren't spending ten times that on mortgage, maintenance, and berthing fees.
Obviously, a TAS membership benefit is significantly more valuable in a no ship campaign.
Obviously, if you run your campaign with different assumptions (for instance a much lower level of interplanetary and interstellar shipping, especially) that would make having a ship much more valuable. And you may not be remotely interested in running adventures like the Harrensa Project, Nomads of the World Ocean, Legends of the Sky Raiders, Tarsus, Ascent to Anekthor, or other such that keep players planetside for lengthy periods of time. No worries. Everyone knows that ship based campaigns work great and there's tons of resources for those. I'm not trying to be like "this is better." I was just hoping for a discussion about how you can thrive without a ship playing Traveller. Even within Charted Space.
