( I´ve noticed that the title of the thread has been changed from "casual" to "family-friendly" in order to justify the comparisons.
Still, most of them are not valid, since NSMB still sells a lot and the latest version of the series are selling proportionally equally the previous ones.
By the way, Mario games have been around since the 80´s, way before casual games were even considered. They do appeal to casuals, but they´re definetely not casual games.
