Discounts
Every price cut of more than 20% we have observed, in each market that quoted one, with this game's chart position on either side of it. These are episodes, not a model: a sale is one event, and one event cannot tell you what the next one will do.
Reviews, worldwide (the counter carries no country): 0/day in the week to Sep 11 → 0/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 26 chart moves that followed a price cut of more than 20% went a median of 7 places towards #1, and the 2,400 moves with no price cut behind them went 2 away. One store, one chart, one country — it is the only place we have enough observations to say even that.
Prices outside the United States have been collected since 6 August 2026 and chart positions since 19 July 2026, so a cut older than that has no market to compare and a market that joined later has no history yet. Nothing here is converted between currencies.
About
Inga Chronicle is a deckbuilding roguelike built on authentic Japanese history — from the Asuka period to the Bakumatsu era. Every card represents a real historical figure, policy, or event. Every combo is a real cause-and-effect chain that shaped Japan.
This isn't a game with a Japanese coat of paint. Its content is derived from Japan's national high school curriculum — the same material tested in university entrance exams. The stronger your grasp of historical causality, the stronger your deck becomes.
Example: Land Reform Chain
"Taika Reform" → "Handen-Shuju Law" → "Konden Einen Shizai Law" → "Rise of Shoen Estates"

Play cards in historically accurate sequences or relationships to trigger powerful [Causal Combos].
The deeper your understanding of historical context and causality, the stronger your deck becomes.
Oda Nobunaga's March to Power:
"Battle of Okehazama" → "Battle of Nagashino" → "Incident at Honno-ji"
Hideyoshi's Centralization:
"Sword Hunt" → "Land Survey (Taiko Kenchi)" → "Kokudaka System"
Sonnō Jōi Ideology:
"Rangaku (Dutch Studies)" → "Kokugaku (National Learning)" → "Mitogaku"
The more you know, the more advantage you gain. The more you play, the more you learn.
