Star Fox fans are too picky...so far I've loved every Star Fox game except Command. No wonder Nintendo doesn't like to make Star Fox games, the fans only like SF64 style Arwing missions, and nothing else but that precise type of mission will do. There's no way to experiment with the franchise or try new things because the fans seem to just want an endless stream of Arwing missions that do the same thing the exact same way as Star Fox 64. You won't hear me defend their constantly retelling the same fucking story over and over again, but I don't really blame them either because the fans seem to only like Star Fox 64 so why would they want a new story either? I used to consider myself a big Star Fox fan but I'm just so alienated from the fan base at this point that I just accept their gatekeeping. You don't think I'm a real fan because I don't only like one game from the series? Fine. I'll just play the games I like and hope that you don't convince Nintendo to stop making them. Y'all are worse than the Sonic fanbase.
Actually, people just like good games. Star Fox 64 is the only good Star Fox game, so as a result it's the only one that people like. Star Fox Zero was extremely traditional, a retelling of the original story yet again, and kept it mostly at on-rails Arwing/Landmaster missions. No one disliked it because it wasn't like Star Fox 64, if anything, it being too like it was one of the reasons people didn't like it.
The reality is that these games have just sucked. Both the SNES Star Fox games are nearly unplayable nowadays because of their choppy framerate; Adventures was an uninspired Zelda knock-off with no real interesting gameplay and clearly not a Star Fox game at heart, on top of adding a lot of non-Star Fox content into the franchise; Assault was an interesting game with good ideas, but terribly executed with some awful controls and bad level design; Command was Command; Zero was a decent reboot of the series, with the best version of the original story so far and getting the character redesigns right, but ultimately failed big time at the same issue as Assault, that being the controls.
