Any nation. Any era. Any decision.

Lead a WWI European power through the July Crisis. Rule a fantasy kingdom surrounded by enemies. Command Rome during the civil wars. Guide a Cold War democracy through nuclear brinkmanship. Build a space empire from a single colony. Survive as a city-state between two giants.

Write your nation. Write your era. The simulation begins from wherever you place it and runs the world accurately from there.

Rivals move on their own timelines. Populations have needs you cannot ignore forever. Armies have limits nobody admits until they matter. Every decision arrives with consequences you didn't plan for.

This is how it always goes. Lead anyway.

▸ Any historical period or fictional setting ▸ Rivals, populations, armies — all independent ▸ Decisions cascade — now, soon, long-term ▸ Era-accurate atmosphere and logic always ▸ All characters adults (18+)

/Custom to write your nation and begin.
