I think the first Metal Gear Solid has aged pretty reasonably. Obviously it doesn't look great, but it still looks like a fairly coherent game overall, unlike many other 3D games from back then, which look just odd. I think the Crash games have aged fairly well too, largely because of the same reason.

If the update haven't made any change it would be quite strange.

And even the original on a 21" CRT would still be playable and nice looking at. Plus the CGIs were just out of this world.

And I find funny people comparing the games on N64 and PS1 to the end of 99 games on PC that basically would be launching on PS2 and GC. Basically cheating the purpose of the thread.

Well, sure, but the topic was which games “aged well”. Aging well doesn’t mean it should still look like it’s a new modern game.

Anyway I’m writing this and the previous post tongue-in-cheek, it doesn’t matter, I just thought it’d be fun to ‘take a gander’.

- Zelda Games
- Banjo Kazooie

You can tell where his mindset is when he states if any of those games were released today they would be ripped to shreds.  Obviously he didn't approach the thread right. 

All good. I intended my response to be a bit more light-hearted than it came across. My bad.

I'm gonna go with the sentiment that 3D Accelerated PC games are really the big ones that have aged well (especially those made in Quake and Unreal engines). And not just games from 1999. Quake, Hexen 2, Quake 2, Heretic 2, and Unreal were all 1998 or earlier. Quake 3 is almost cheating because it was released in Dec 1999.

N64 games have aged worse, but not as poorly as nearly every 3D PS1 game. Even with an emulator with a resolution boost and post processing, PS1 games just look like a mess.

Yes! In my list I forgot Heretic 2, if we don't consider later mods, that can make many games with scalable engines look good even for modern standards, see for example Morrowind, that was already really gorgeous, even compared to most of the other games using the Quake 2 engine. Unreal was gorgeous too, but it had the advantage of using a more recent engine. Heretic 2 OTOH achieved results as good using a tweaked Quake 2 engine, the first time I played it, it made my jaw drop even comparing it to Quake 2 that still was one of the best. It's use of lighting to create atmosphere is still one of the best I've ever seen.
Hexen 2 OTOH disappointed me a little bit, yep, IIRC it used a tweaked Quake 1, not 2, engine, but that wasn't the problem, I just think that while Heretic 2 changed the old Hexen/Heretic style for something both new and really great, Hexen 2 just didn't manage to make its new style great too.

In terms of the actual game, yeah, I was slightly disappointed by Hexen 2.  I just think Hexen (the high water mark of the series, imo) was a hard game to top.  And yeah, Hexen 2 used the Quake 1 engine.

F-Zero X is another great example I feel.

It runs at 60fps which was rare for 3D console games of the time, and like Starfox 64 its design sidesteps the camera and control problems of a lot of early 3D titles.

Still plays like a dream over 20 years later.
