Perfect10 is a cancelled adventure racing game that was in development around 2003 by Rage Games Birmingham. We don’t know much about its gameplay, but we can speculate it could have been similar to Road Trip Adventure (Choro Q HG 2), with a big open world to freely explore while driving around doing quests.
The project was never officially announced by the company and only a few 3D models / concept art were found online, preserved in the gallery below to remember its existence. As we can read on Wikipedia in 2000 Rage began to expand into publishing. However, the costs of publishing and a run of games that did not sell as expected eventually led to the company closing in January 2003 due to bankruptcy.
