Update: Making progress on mercenary system. The UI is in and working. The system is integrated with the current morale system (mercenary morale isn't affected by civ happiness; it has baseline 0, or -20 if you are at war with the merc's civ of origin). AI is always a lot of work though. Right now I'm getting AI players to know when to hire and when to put up units for hire based on their own relative strength and current threats (a Mercenary CS will take all units off the market if a mass of units is moving toward it). Some civs are "suppliers", which includes all Mercenary City States and military-oriented full civs that have the Mercenaries policy. Others are "users", which includes most other city states and full civs that are not so military-oriented. A full civ can hire without the Mercenaries policy if they are friends with the CS or full civ supplier. A CS can hire from any supplier. Some city states and full civs are neither suppliers nor users. Post Lua log for these. I can often spot the problem and get a fix out very quickly. It's planned, but I probably won't get around to this for a while. I need to make sure all the primary naming conditions/traits are working and interesting.
