- Content Leak: The existence of the North American and European 3DS releases were prematurely revealed as a result of a few pages being published onto Atlus USA's website by accident. The same leak also revealed localizations of Shin Megami Tensei: Strange Journey Redux and Etrian Odyssey V: Beyond the Myth.
- No Export for You: The original game didn't reach Europe, though at least the DS is region free. Averted with the Updated Re-release on the 3DS.
- What Could Have Been:
- The initial idea for the game had two more countries involved and no Alternate Timeline.
- The original progatonist was supposed to be a living sword. Stocke and Eruca were also supporting characters instead of the leads.
- Marco and Raynie didn't exist in the original story, and their role as Sacrificial Lambs in the prologue was intended for two generic soldiers.
- The Wiki Rule: Radiant Historia Wiki.
