Please Amazon… If this fail please release the project as open source.
I would do a mod where factions are at war. Inside territory of your own faction you have the option to flag pvp but if you enter another factions territory you would be flagged.
Towns would benefit the entire faction.
Taxmoney would go to townboard rewards… A popular town like everfall would give higher townrewards than un popular cities…
Each realm get a main city that cant be taken (but can be raided)…
Something like that…
