General Problem with assumption: Why would players be 1 week in starport?

[Spinward Flow]

The potential is there, but very little write ups of complete star systems.

Maybe not.
But Traveller Worlds does exist in the current timeline.
You don't HAVE TO make everything up from scratch anymore ...
You CAN (if you want to) ... but you don't HAVE TO ...

You can make up an entire system using nothing more than LBB:3

Generate the mainworld as normal. Roll or decide how many planets there are in the system. Generate them with one or two changes - population should be at least 1 less than the main world, government type and law level can be set as being the same as the mainworld if you want, or roll if you want a bit more fun...

The biggest problem for me is always atmosphere, and possibly hydrographics. I would convert any non-tainted Thin/Standard/Dense atmosphere for a non-Mainworld to Exotic of the same pressure. Tainted might remain the same, or become corrosive in the Inner Zone, and become Nitrogen or trace and/or frozen to the surface in the outer zone, depending on world size.

Hydrographics in the outer-zone is ice (or sub-surface ocean), is "0" in the Inner zone.

Unless of course there is another world around a companion star in the system in its habitable zone which might be somewhat "shirtsleeve environment" . . .
