You realize that 3D Land & 3D World fall under the 3D Mario category (like the Galaxy games, 64, & Sunshine), right?
Well, they don't, do they? I appreciate that it's subjective, to a degree, but 3D Land and 3D World seem like a hybrid between the two. There's no free-look camera in either games - a feature that's present in both Galaxy and Sunshine. It's (almost) fixed perspective. 3D Land and World are also much more platform/'stage' based - few open "roamable" spaces and a lack of organic stage design. Y'know, everything's kinda tiled? It offers a far more linear (in many ways a good thing!) approach to gameplay, but inhibits natural control/exploration.
'64 had a good mix - it kept the puzzle style platform stages to the Bowser levels and some other worlds (Tick Tock Clock, kinda), whilst still maintaining an explorable 3D map for many other levels (Bob-Omb Battlefield, Hazy Maze Cave, Fuckin' Penguin Land).
Do you see where I'm coming from with this? I'm not outright attacking the recent Mario games, but they all follow a similar formula, and after a while this begins to feel monotonous.
