I don't know about coding yet... Woodelf's probably right: better to see what we need doing before starting.
I now have flags and leaders for all 15 civs. In each of the three civ. categories, two dominant ones have two leaders - all the others have one.
I have assigned leader traits and have replaced 'financial' with 'populous'. There are eleven in all: as well as the eight normal ones, there are three others, which come with major bonuses and some handicaps attatched - these are 'Economic', 'Scientific', and 'Domestic' - Each civ has one of these mega-traits in addition to two others which come with the leader(s).
The traits are: Aggressive, Creative, Diplomatic, Expansive, Industrious, Organised, Philosophical, and Populous.
I am compiling a little bible with all the proposed terrains, civs, traits, leaders, civics, &c in it.
Things we need to brainstorm are units, unique units, technologies and city improvements.
I'll post the bible when it's finished.
Here are some more flags:
In order: Alliance (independent), Coalition (ind.), Lunar Prospecting Corporation (commercial), Orbital Limited (comm.), Organisation of Space Exploration Corporations (comm.),
2nd row: Republic (ind.), Universal Business Industries (comm.), Unified Trade Authority (comm.), Federation (ind.), Union (ind.)
Hopefully they're all sufficiently unique and varied so as not to pose an identification problem...
