I think this could get all quite complicated real quick. So we'd probably need to split it into several separate steps, starting with the simple ones. For starters, I'd imagine: - Having the town guards actually care if you're hostile - Maybe have them automatically initiate dialog in some cases - Plus your suggestion to have town folk be able to report you too - Adding a preprocessor for all player to NPC address forms to indicate the flag you're flying That together is probably already a considerable job. But it could lead to interesting sneaking around enemy towns! Dynamic false flag detection while ashore probably needs to wait until the AI groups are finally working right again.
