>>299077093D World isn't a true 3D Mario in the way 3D Mario fans want their games to be.
3D Land and 3D World are 2D level design philosophies adapted into 3D (follow a linear path and get to the flagpole, sometimes fighting a boss at the end of a linear path instead), as opposed to traditional 3D Mario level design (multiple objectives within a single level, various goals to accomplish like platforming/solving puzzles/fighting bosses with various methods/collecting items/misc. instead of being limited to platforming and the occasional boss that is always defeated by jumping on it, objectives sometimes being obsuficated and forcing you to explore instead of always being a linear path to follow).
I like 3D World, but it's not a 3D Mario game at heart, it's a 2D Mario game put into a 3D engine. This isn't a bad thing, and I usually prefer 2D Mario to 3D Mario
also SMB3 > SMW while I'm discussing tastes, but it should be easily understood why it's not what 3D Mario fans are looking for. Fortunately a lot of Mario fans like both the 2D and 3D games so they still enjoy 3D World.
