If we're arguing in terms of 'Mature' related content on the Gamecube...
Let us not forget the entire spectrum of Resident Evil games on the Gamecube (one of which is exclusive; one of which, in terms of being a remake, is exclusive, and one of which
was an exclusive) as well as Killer 7 (which was, at one point, an apparent exclusive, as part of the "Capcom Five"), MGS: Twin Snakes (remake exclusively for GC) and Geist (which has, actually, remained an exclusive and was also published by Nintendo).
In addition to other third-party fare, such as the Prince of Persia games, the Splinter Cell games, Gun, etc.
That is, in the broader sense. If one were to focus on titles Nintendo has actually directly connected itself to, that'd mainly be limited to Geist, Eternal Darkness, and (I believe) the Twin Snakes remake.
