It's funny thinking about how I used to say that it was an unpopular opinion that the Game Theorists didn't know what they were talking about. Fandom perceptions can really change in a couple years!
Here's a real unpopular opinion: I think Super Mario 64 has not aged well, and although I recognize that it did a lot for Mario and is obviously an important part of history, the shadow it casts on newer games that are, quite frankly, better than it seems unfair. Super Mario Odyssey and Super Mario Galaxy are superior games by far, with better direction (art, story, and gameplay wise) and better graphics (yes, SM64's graphics are that way because of the hardware at the time, but that doesn't change the fact that SMO and SMG are far better looking games, and SMG in particular is impressive given that it has aged pretty well despite being a Wii title). To put it succinctly: they clearly knew more what they were doing with SMG and SMO than with SM64 and it shows.
EDIT: I did not read all the replies before this and it shows. Sorry about that. I stand by what I said here, though.
