Rekiden II is a browser-based historical simulation game that reinterprets history as a system of constrained decisions rather than a sequence of heroic actions.
Set in late Sengoku-period Japan, the game follows the life and rule of Uesugi Kagekatsu, progressing strictly along historical events while allowing the player to experience how state-level decision-making structures collapse, shrink, or survive under political and military pressure.
This is not a "what-if" history. This is a simulation of why things could not go otherwise.
In Rekiden II, the visible protagonist is a historical figure. The true protagonist, however, is the state decision-making structure.
The player believes they are controlling choices. In reality, they are interacting with a Finite State Machine (FSM) that restricts which actions are even possible.
Correct decisions can still lead to failure. Moral actions can still result in loss. Survival is not victory.
-
Historically Fixed Timeline
Events follow recorded history. The player cannot rewrite outcomes. -
FSM-Based State Control
Political, military, and economic states determine which actions are available. -
Critical Historical Events as State Triggers
- The Naoe Letter
- The Battle of Sekigahara
- The Aizu Relocation and Domain Reduction
-
Illusion of Control
The interface presents agency while the underlying system steadily removes it. -
No Win Condition
The only terminal states are survival, marginalization, or collapse.
Uesugi Kagekatsu was neither incompetent nor reckless. He made few objectively catastrophic decisions.
Yet his domain declined.
This makes him an ideal subject to demonstrate how:
- Individual intent fails against systemic constraints
- Loyalty and rationality do not guarantee success
- Political systems punish structural misalignment, not just mistakes
- Not a power fantasy
- Not an alternate history generator
- Not a tactical war simulator
- Not a character-driven RPG
- Pure HTML / CSS / JavaScript
- No server-side code
- Fully static deployment via GitHub Pages
- Game state stored locally in the browser
This project is experimental and intentionally minimal. The focus is on structure, not spectacle.
Expect:
- Text-heavy presentation
- Sparse UI
- Uncomfortable outcomes
