Thank you for the kind words. I have plans to expand these rules at some point to include starship pursuit rules among other things, but for now I'm happy with the one-page.
The setting is Traveller's Third Imperium, but I can't say that in the document due to legal IP reasons. I did hint at it heavily, though. :)
Regarding the occupation table, that's intentional (and also why the option to simply choose an occupation is included).
