Just remembered another one: the Mega Man: Battle Network series. It started off with a metacritic of about ~80 and started going down to about ~60, but you gotta admire how the developers translated Mega Man Classic game mechanics (choosing the right weapon for a situation, dodging enemy attack patterns) into an RPG! Most criticisms of the later games go along the lines that they don't innovate much from their previous games, but this is Mega Man we're talking about :/
and perhaps also the Final Fantasy Crystal Chronicles series. They're games which thrive on multiplayer dungeon crawling, but nobody seems to own the equipment to play them. Playing through the DS game I kept thinking "man, this would be so great in multiplayer"
