I used to like Mario Kart 64 a lot when playing years ago. But I dunno man, when you're turning it feels like you're sliding on ice. Personally I like later entries as I felt like I was more in control
I loved Mario kart 64 when I played it as a kid, so much, was one of my favourite games to play and I played it again recently and it's a very simple game. Mario kart was really one of those series that each game is objectively much better or at least more expanded than the last in the case of mario kart on the wii just being a retooled double dash. Mario Kart 8 is the best mario kart in every way.
The following takes on classics might shock some, but I am seemingly immune to the concept of nostalgia when it comes to something I can enjoy in the present, in this very moment as opposed to just remembering something, If I enjoyed something years ago and play it now, if it's really dated in too many ways, I admit it's not as good as it was at the time or the game was always mechanically sound and has "aged well". I should add that I played all these games on release, bar xenogears.
For me a game that aged badly would be Final Fantasy 7, everything about the game when it came out was spectacular, except for the dialogue not being great(had no idea about the rushed translation at the time) and the character models outside of battle looked weird to me, even at the time, likely a compromise based on what was likely an early N64 build if the character models of 8 and 9, parasite eve and even xenogears are anything to go by, FF7's character models look so strange compared to literally everything square did at the time on every game afterwards for the PlayStation, conjecture on my part of course but if the FMV's were removed and the audio was formatted differently, it would work as an early N64 game. It genuinely looks like it was built for the N64 and it's well known that it was in development for the N64 and they abandoned it because Nintendo went with cartridges instead of discs, square needed more than the amount of space that was on a N64 cart. This is my theory for why the FF7 character models aged like milk.
I played FF7 on it's release, I rented it, I bought it later when it was released as a budget title, after finishing 8. I replayed 8 and 10 throughout the years but never 7, played through 7 twice and didn't touch it for a while. Like everyone else I was hyped when cloud showed up in kingdom hearts, and I remembered the music, characters and story pretty well. I started to remember it looking a certain way, "How I remember it looking".
Advent children was about to release so I thought I'd play through it again. I was horrified. I loved advent children and dirge of Cerberus as it was more of 7, but as I remember it looking. There's many that hate the new 7 games, but I adore them as it's what I wanted from it, but with extras and a pseudo sequel at the same time. I took my sweet time playing remake, got 50 hours out of it and relished every second.
I took a break from rebirth after 90 hours as I'm half way through, and needed to focus on studying for university exams, however, I am old school day 1 fan of Final Fantasy 7 and the new games are objectively better in every single conceivable way. It's like comparing Mario kart 8 to Mario kart 64. I think FF7 is a prime example of a game that was great at the time but aged poorly in all the mechanical ways, not the music, story, area design , character design etc. Is a decent game, but it's not the masterpiece that those blinded by nostalgia claim it is, as it's aged badly in a few ways.
I really can't understand why anyone born way past it's original release, sitting down and playing it now or in the last year for the first time, and claiming with a straight face, that remake and rebirth are objectively worse games that the original. It's ironically what the team would have done at the time if they had the resources available. It's why so much effort was put into advent children visually and they wouldn't touch remaking 7 until it could look as good as advent children, of course, remake and rebirth look better than advent children did.
Resident Evil 4 is also very stiff mechanically, bought that game day one, played it several hundred times throughout the years, the remake is a massive improvement on it. Leon feels like he's running between two rails when he's moving, instead of the buttery smooth movement of the remake. RE4 OG is important though, it changed action games forever.
Old games require adjusting to dated technology, this isn't really an issue from the 16 bit era onwards for 2d games, as they all aged great for the most part. But the early ps2 era and earlier, many of those games made choices due to technological limits at the time that made the game "dated".
I am currently playing through xenogears, I played xenosaga 2 many moons ago and we did not get the first or third part, we didn't xenogears either in Europe so I'm playing Takahashi's games in order of release. It's amazing but clearly made by a team at squaresoft around the same time as FF7, it reminds of FF7 in subtle ways I can't quite describe. Though many things about it aged better than FF7 for the most part. Bad camera is my main complaint and slow text crawl, otherwise it's pretty great. I am not counting the shortcomings of the game essentially running out of budget and time as it wasn't a massive budget title as anything to do with when it came out.
The original resident evil 1 also really didn't age that well, tank controls were a bad idea. The dialogue is atrocious too. 2 aged well, though in all honesty those fixed camera angle tank control games require adjustment to enjoy. I often thought I want to play through RE2 again and I'm just thinking "oh yeah...the controls D:" and stop playing. Nintendo focus on how fun it is to move a character around as the starting point for making games, and I agree, movement should be fun before anything else.
Mario 64 didn't age too well graphically, but the gameplay is just as good as when it came out, still great, even if the levels aren't as well designed as every other game that came after. Nintendo's logic of movement should be fun worked out.
