Retro Studios, in association with Nintendo, has had most of its games produced by one person.
Retro began with 4 key people in late 1998 and opened an office in Austin, Texas in early 1999 with a staff of 25 people, including several former Iguana employees. Despite not having access to GameCube development kits, the studio immediately began work on four projects for the GameCube: an untitled action adventure game (with a working title of Action-Adventure), a vehicular combat game with the working title Car Combat (also known as Thunder Rally), an American football simulator named NFL Retro Football, and role-playing game Raven Blade. By the time development began, the studio had already grown in size to 120 employees. The company continued to grow during production, eventually peaking at over 200 employees.
