Tons of people dedicate channels
And it happens to be the one channel from someone that has plenty of experience with normal racing games...so was doing his own analysis of most antigravity racers to a strict degree, and he felt like the game was actually not deserving of the difficulty label instead calling it skill issue. Emphasis on he and not anyone else (not counting people on the comments that may agree with the video)
There's always game specialists anywhere even for the most complex games, but I think this one case of a guy that is acquainted enough with racers (including F-Zero X, which he likes more than GX) to breeze through one of GX's most infamous challenges and using that as base for every GX player calling it skill issue/being elitist because they find it easy isn't quite right.
Not to say that there isn't elitist players, but I know there's also very skilled players that are humble and/of respectful, as well as there are players that enjoy the game even when they aren't complete masters of it.
I myself had suffered a lot a few years ago to complete Diamond Cup in Master as I had to perform well in the first four races AND kill the rival at the start of Phantom Road because I was unable to get high positions on that track lol
And for as how I like GX, I'm aware that it has a lot of quirks that can make it tough for newcomers (reliance on precise steering with the analog stick, replaying to learn tracks and use reflexes, the lack of an in-game tutorial to learn the ropes on your own), so it's not that I can't understand why you felt disappointed (you even pointed it out clearly: You played the original F-Zero for casual fun racing, but GX is made for high speed specialists).
I just felt that trying to encompass all GX enjoyers into that image of "it's just skill issue bro" wasn't right - as I mentioned before, GX for many is known to be quite tough instead of the complete opposite, so its mainly those who have mastered it (whether the basic handling or every button in the controller) to a high degree that could somehow call off the hardest challenges of it as easy.
I guess the Elden Ring comparison may be apt in that regard lol
Rant done, now curious on if you've played F-Zero X and how you feel about it. Or maybe even the GBA games which seem closer to SNES (more so Maximum Velocity even if it plays a bit weirder, but GP Legend and Climax do add X/GX elements to the Mode 7 gameplay and could be more casual friendly)
