Imo, you can’t give something the title of “best” purely on the idea that it was influencial. Kirby’s Dreamland, for example, set the tone for the entire rest of the series, but Kirby’s Adventure is objectively just better, and Kirby Super Star Ultra contains the entirety of Kirby’s Dreamland inside of it (albeit with enhanced graphics, and new mechanics). Now, if you still like Dreamland, because Kirby doesn’t need all these newfangled copy abilities, well, that’s fine, but to say Dreamland is better purely because it laid the groundwork isn’t a good argument, imo.

Ultimately, it comes down to how you define best. I took it as the level of satisfaction at the time of play. The enjoyment and "wow" factor of a game is greatly impacted by the historical precedents and available options of the market at the time. 64 completely revolutionized how I understood platforming to be, it took my breath away. I have only really had that sensation a few times since. So while Odyssey might objectively be a better game, it doesn't have that X factor which really floored me. There is nothing unique about it that I can't get anywhere else. But like I said, it depends on how you define best.

I'm surprised people aren't voting Galaxy. I normally see them ranked pretty much the highest.
