The first released title by Templar Games, UTB: The Tournament was intended as a stand-alone demo/side-story to showcase my game-making capabilities for several makers' fairs being held in Detroit. As a self-contained story, The Tournament can be played independently of any other titles in the series, though, as it takes place a year before Unto the Breach itself, it's recommended playing this first if you want to experience things chronologically.
Since this version was developed in RPG Maker XP, it's not compatible with the current version of RPG Maker the main game is being developed in, and thus can't be directly added in. I might go back and add it as an optional side-story of some sort later on, as the events of The Tournament are referenced in the main story.
The Tournament is a free game, available for download.
