My custom Mongoose Traveller GM screen
(ttrpg.network)
For my Mongoose 2E campaign, I made my own custom GM screen, with only the stuff I found myself needing on a regular basis. It's 3 landscape pages, designed to be put in a customizable GM screen.
You can download a PDF copy, and the original Affinity files I created it with, here: https://polyhedralnonsense.com/2025/10/09/a-custom-gm-screen-for-traveller/
Haven’t delved too deep trying to find differences. From what I can tell, Cepheus Engine is pretty much the Traveller SRD.
According to this blog, CE also took bits from other SRDs: http://theotherside.timsbrannan.com/2022/05/review-traveller-and-cepheus-srds.html?m=1
