Sengoku Space Opera

Background

About 15 years ago I was part of the team that developed the shogun, a browser strategy game that launched in Japan. After a few more titles I left the games industry, and I've been working as a developer in other fields ever since. Around two years ago I started using AI in my day job, and watching how fast it kept evolving made me think I could revisit the genre I once enjoyed making — with AI as my co-developer, this time as a completely new concept rather than a continuation. This project began as that experiment. I handle the director and PM roles while AI handles planning, code, art, and infrastructure.

There's plenty of skepticism toward AI-developed games, but the one thing I've felt throughout this build is that a director's burden stays exactly the same, whether the team is AI or human. The weight of judgment needed to steer a project toward the vision you want doesn't change.

About the Game

"Tenka Tōitsu (天下統一) — unification of the realm, right in your hand, across the vast Opera Sector."

You play as a daimyō (大名) summoned across dimensions, leading cybernetically-augmented Sengoku warlords (武将) from a massive Mothership anchored in deep space, competing for the throne of Shōgun (将軍). The strategic depth of 2000s-era browser strategy games — type matchups, fusion, deck-building, resource bottlenecks — is preserved intact, then layered with Sengoku-era Japan IP and a sci-fi universe. The tile map is gone, replaced by a list-based UI so a meaningful one-handed action is always within 15 seconds of opening the app. The core play: collect and grow 30 warlord cards, build them into a three-lane fleet, and expand your 8-module Mothership.

Roadmap

The current build is a single-player MVP. This release exists to validate whether the core loop — economy, growth, NPC combat, reward — is actually fun. More to follow in phases:

• Phase 2 — World exploration (nearby players, trade ships, asteroid belts), satellite-ship siege, resource plunder
• Phase 3 — Mutual defense pacts (1:1 alliances, up to 5), coordinated ops, chat & diplomacy
• Phase 4 — 90-day seasons, Season Pass, rankings, the Kyoto Prime campaign

⚠️ Notice: This Is an In-Development Build

The version currently available is a development build. For reasons such as balance changes, data-structure updates, or new feature rollouts, server data (warlord cards, Mothership progress, resources, etc.) may be reset without notice. This build exists to validate the core loop and its fun factor — please understand that progress made here may not carry over to the final release.

I'd Love Your Feedback

Your reactions — feel, balance, UX, anything — will directly shape the next build. Whatever worked or didn't, please leave a note.
