I have explained my reasons and they are different from the wider Mega Drive vs Genesis debate You just don t happen to agree with them The issue is that the Genesis is a subset of Mega Drive being only a single variant not the other way round So technically this is a Mega Drive game especially since it was developed in Japan regional specifics of the subject are also to be considered in issues regarding international variances If it was only released in North America then I would have no issue with referring to it as a Genesis game
