My problem with that video is that you say Mario 64 is the "best" 3D Mario, but defend that with why it was transformative and impactful. Those are reasons for it to be the most important 3D Mario, but not the best. I mean, maybe for you it was still the best, and that's fine, but I don't like the reasoning you use there.
My list of "best" would be:
1. Galaxy 1
The only 3D Mario I could play forever and never stop. Hell, I could spend an hour just running/jumping/flying around Rosalina's ship listening to the music.
2a. 3D World
Finally, a Mario game with multiple levels that I can dump dozens of lives into and yet still be determined to go back and do it right.
2b. Galaxy 2
The reversion from a hub world to a flat, boring 2D map = bad, but they also added Yoshi, and once you're in the levels it was good times, so...
4. Mario 64
Yes, the jump to 3D was massive, but looking back at it now, it's really not that difficult of a game; playing it now, nearly all my deaths are from fighting with the camera. I do give it the award for best final Bowser boss fight, though.
5. 3D Land
I have this game, I 100%ed this game, and yet the only thing I can remember about it is the one level where you use the 3D to jump nearly vertically down a waterfall. I think. Maybe it was clouds? That's my problem though; this game is utterly unmemorable to me.
9. Sunshine
Yes, 9. I rank three 3 slots of nothing ahead of this game. The camera was horrible, the movement controls are stiff, and while as mentioned I LOVE me some 3D hub worlds, this one was just unnecessarily convoluted - there's a big difference between "I have to get from A to B and it'll take a while (see: Banjo-Kazooie)" and "I seriously have no idea where the bleep I'm supposed to go". Give me this game with Galaxy's controls and camera system, and then we can talk.
