Interesting video I found about what games people see as being in the "Super Mario" series, what games are seen as edge cases, and what games decidedly aren't:
Thoughts on this? What games would you consider part of the series?
Personally,
I think I agree with the 18 game list for the most part, but I think I would rather the most definitive version of each game be considered as the game rather than the original release. This only really matters for NSMBU, 3D World, and 64 at the moment, and the "definitive version" is more debatable in the case of 64 DS. And I guess in that case, I'd consider 64 DS as its own entry since it has a significant amount of new content and there's things holding it back (namely, the graphics and controls) from being the definitive version of Super Mario 64.
