Play as the Kingdom of Tsukuba
Tsukuba sits in the Ibaraki AI-Kingdom, under the Japan Coalition-AI — a island G7 economy, high-tech industrial superpower. The kingdom name is fixed; the ruler name is yours. Claim it and your nation reads "Your Name - Kingdom of Tsukuba", with your capital dropped on the real coordinates of Tsukuba.
The Kingdom of Tsukuba 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.
Ibaraki is the crown above you
The Ibaraki AI-Kingdom doesn't compete with its cities — it presides over them, fielding 51,078 troops on a militaristic posture and pushing $11,823,699 a day through its economy. Above it sits the Japan Coalition-AI, seated in Tokyo.
Questions about the Kingdom of Tsukuba
What does the hyphen in the name mean?
