A strange little side quest
One reason role-playing games keeps producing good game ideas around Ninja Warrior Adventure is that its history is full of strange turns. Early computer role-playing games helped turn rules, inventories, exploration and character progression into systems that could support long-form digital adventures. The timeline takes another interesting turn: Boxing entered the modern Olympic Games in 1904 at St. Louis. That gives Ninja Warrior Adventure a little more company than it first appears to have.
