Scooby Doo: The First Mystery

Scooby Doo: The First Mystery is an adventure video game released in 2003 for the GameCube, XBOX and PlayStation 2.

Development
It was originally a collaboration between Cor-Son Games and Heavy Iron Studios, but the latter left to pursue their deal with Nickelodeon to produce SpongeBob Squarepants: Battle for Bikini Bottom. Cor-Son later received assistance from their prime developing partner High Voltage Software, with additional work by Artificial Mind and Movement (who was hired to develop Scooby-Doo games).

The game was intended to be a sequel to Scooby-Doo: Night of 100 Frights, but its story was later altered to give a more unique take on the Scooby-Doo series. Cor-Son Games worked on the character designs and story, while High Voltage Software and A2M worked on implementation, along with using assets Cor-Son acquired from Heavy Iron back when they were still on the development team.

Gameplay
The game has both 3D platforms elements and sandbox elements. You get missions by talking to people and you collect evidence for the ghost you're tracking down. You also get to fight demons that the ghost throws your way.

Reception
The game was met with mixed to average reviews. Praise was put toward the story, though its lack of connection to the spirit of the Scooby-Doo series was criticized. The gameplay also wrought mixed opinions, with the implementation being commended, but the sometimes simple nature being held against it.
