A prototype Space Trader Game. You can buy and sell a selection of goods within the nine Core Systems. It's fully functional, with all the basic mechanics done.
On my list for expanding it:
A bigger universe,
Learning JSON to put the data in a better format,
Repair, refuel, upgrade and buy new ships and parts,
Diplomacy and role-playing, complete with background stories for pilot and crew,
Recruiting crew to fly bigger ships,
Setting up supply and distribution lines,
and... and... whatever else I can think of. (Not interested in manually flying my spaceship, though, or combat/raiders/pirates).
