Play as the Kingdom of San Diego
San Diego sits in the Cartago Province AI-Kingdom, under the Costa Rica Coalition-AI — a no-army Central American democracy, eco-tourism model. The kingdom name is fixed; the ruler name is yours. Claim it and your nation reads "Your Name - Kingdom of San Diego", with your capital dropped on the real coordinates of San Diego.
The Kingdom of San Diego shares what it holds
City kingdoms carry 50% more money and resources than an ordinary province, and they trade what they hold with their own ruler and allies.
Cartago Province is the crown above you
The Cartago Province AI-Kingdom doesn't compete with its cities — it presides over them, fielding 23,365 troops on a balanced posture and pushing $5,104,132 a day through its economy. Above it sits the Costa Rica Coalition-AI, seated in San José.

Questions about the Kingdom of San Diego
Is playing from San Diego free?
Completely. No download, no paywall, and it works on phone or desktop.
Can someone attack the Kingdom of San Diego?
Yes — other real players and AI nations can declare war. Build infrastructure and happiness before you build an army, or upkeep eats you before an enemy does.
What do I get for claiming San Diego?
A sovereign city kingdom with 50% more treasury and shareable resources than an ordinary province, a real-world map position, and the coalition's armies within diplomatic reach.
Is San Diego part of an AI coalition?
Yes. San Diego sits inside the Cartago Province AI-Kingdom, which answers to the Costa Rica Coalition-AI. The coalition presides, the kingdom governs, and you rule the city.
What does the hyphen in the name mean?
Everything before the hyphen is yours — your chosen ruler or dynasty name. Everything after it is the AI-Kingdom title you claimed, so "Kingdom of San Diego" stays fixed while your name leads it.
