Overview

Why this game lands differently

History becomes your combo logic

The order of events matters. When you understand why one event leads to another, your deck starts producing stronger turns.

Understanding becomes your edge

This is not history pasted onto a card game. The historical chain itself is part of the strategy, the reward loop, and the route you build.

Short demo, clear hook

The current demo is built to quickly show the core loop: choose an approach, chain historical causality, and push deeper with better judgment.

Cause-and-effect combos

A sample combo chain

Battle of Okehazama → Battle of Nagashino → Honno-ji Incident

When the flow of history lines up, the chain becomes a strong Sengoku route combo.

Game flow

What a run looks like

1. Choose your hero

Different heroes give you different strengths, card pools, and ways to approach a run.

2. Move through historical routes

Advance through events, pick rewards, and shape a route that can keep paying off later.

3. Trigger linked events

Line up the order correctly and the board state starts rewarding historical logic.

4. Push deeper with better understanding

The more the structure of history makes sense to you, the more strategic options open up on the next turn and the next run.
