There are two disparate components of Sonic Chronicles: The Dark Brotherhood, each of which has its own fandom. Sonic the Hedgehog, and BioWare. These are pretty distinct things: Sonic is traditionally the domain of retrogamers and children, and is best known as a series of action-platformers; BioWare makes a lot of complicated role-playing games, some of which are even on computers.
If you find yourself interested in Chronicles, why? Is it more because of the characters or the developer? It's certainly not the name.
