Okay, and one more thing: there's more going on with characters in the Sonic and MMX franchises than in the Mario franchise, so despite the Sonic and MMX franchises also being "character" oriented, people don't see Sonic's rivalry with Robotnik or X's rivalry with Zero to be completely representative of their respective series. So those rivalries would be more or less the same tier as Samus/Ridley, which is the main rivalry going on in a series that no one plays for characters.
Sincerest apologies for taking up so many posts.
