hmm, its hard for me to really point out problems with the graphics of this game since i played a bunch in the past (and still do occasionally when theres time), and im also pretty used to the driving and camera as well so while i dont really understand what you mean by aging well, i can say its pretty good for snes graphics since the topic was a bit mediocre back then compared to now which is super amazing and attractive to me heh
as far as looking back at graphics some number years ago and now is, i think people in the present age so to speak would probably call the graphics trash or talk down about that, but when you arent around to see it its kinda hard to blame people for that tbh. while they are in fact 'bad' compared to now, the game was still plenty fun but the lack of drift efficiency made the special cup and even some courses in the star cup tougher than they couldve been otherwise, but since snes didnt have the capacity for this feature, i cant call it a surprise either. the game is still fun if youre in the mood to go back to older games, but one thing i loved about mario kart wii and all else that came after it was the option for an auto drift which was easy on my fingers since i have small hands and holding or drift spamming manually gets kinda painful for me a bit more quickly than id like. the alternative we had in this game though was being able to lightly tap the button to take curves more smoothly which is do-able, but a drift option is best for tricky turns that were in certain courses.
