A prequel to the acclaimed role-playing series Suikoden, Suikoden IV reveals the origins of the Rune of Punishment. Although set in the past, Suikoden IV has no shortage of innovation, as it features a Tactical Formation System and more than 60 playable characters. It also has some important first for the series- such as all travel is done by ship, and characters are imbued with actual voices- among other features.
