The texture quality is rubbish, but that's not unusual for remakes from this era. In my mind, I feel like I remember the sense of speed feeling slower on this game because of the lower framerate, but it runs smoothly and feels fast.
I have a lot of nostalgia for this game. To be honest, I still have a lot of nostalgia for Episode One - I don't think I could watch it and enjoy it now, but I was ten when I saw it and I thought it was incredibly cool. I played the game a ton and it was one of my favourite N64 racers. I only had an N64 (and played PC games), so I feel like I got used to slower framerates in racing games - Extreme-G and Diddy Kong Racing are both games that I loved, but in hindsight I can actually remember them feeling slower. I don't know how long the nostalgia will last, but having a portable version of a game that is near and dear to my heart is a nice, warm, fuzzy feeling, especially since I had no idea that a remake was in the works.
It's £12.29 on Switch, which is probably a bit too expensive if you don't have the nostalgia for the game, but if you're an N64 kid like I am I'd recommend checking it out. Now we just need to start the petition for an Extreme-G remake, right? And also, why hasn't there been a new F-Zero game in forever? F-Zero X was just about the only racing game on N64 that DID have a good framerate and sense of speed, and it's probably the best of the bunch even if it's not my favourite.
