“Distant Stars Arising” is a project to develop a “quick play” 2D6 SF/Cepheus/Traveller system that uses a VERY condensed rule set (currently 32 pages) and cards to help with most aspects of navigation and plot (not just, or even really, weapon/kit/NPC cards).
Here's an example of the layout for the area of space around where the Travellers are:
And here's the system they're in.
To support play here is a Consolidated List of Online 2D6 Tools - my faves from other people, and my own.
Here's a draft Meta-Task Resolution System. dsa_-_metatask_resolution_system.pdf
