It's funny you mention SS2, I've been having trouble getting the copy my friend loaned me (they felt bad my ex-roommate swiped mine) patching to 4.4. It just seems to crash with it, can you suggest possible solution? I forgot how much I loved that game, though I had to get used to S being the crouch key and not back up. I forgot about that LOL.

My list would include (some previously mentioned):
Grim Fandango
Nocturne
Shin Megami Tensei 3: Nocturne
Shadow Hearts 1-3
Full Throttle
Neverwinter Nights
Sanitarium
Dragon's Lair 1+2
Braindead 13
Space Ace
System Shock 2
Most of the Jedi Knight series
Actually...most Lucus Arts games are beautiful even today.

Well, Space Invaders, Tetris and Ms Pac Man haven't aged particularly well graphically, but they're still perfectly playable. As much as I love 8bit games, it still always feels like a bunch of Legos are attacking each other. But Super Mario World (the SNES one) still looks amazingly good today, though, as do most of the 16- and 32-bit 2D games.

I still think Doom looks good. I think it looks better than Heretic and Hexen even though they're newer and on the same engine. (I think that has something to do with those games having more melee enemies, though. You see the sprites up close a lot more often than you do in Doom.)

Another World looks great to this day.

I don't have a problem with old graphics in 99% of the games. Even games from infamous "they just invented 3D" era, also FMV games with 3D backgrounds (backgrounds look pretty bad, but the rest of the game usually is ok, duh, if you like FMV games)

But I just can't stand the graphics like in Might and Magic 7 and 8. Horrible, simply horrible.

I don't mind the outdated engines. Aesthetics and artistic integrity are what's important. And M&M7 and 8 would be the same fucking ugly back then, as they are today.

Star Control 2. It has a simple, colorful design that always appeals to me.

Pretty much, yep.

Simcity

I read those posts and thought that what a rip.. nothing are so old. or am I..

rpg games usually will stay the longest. So I would say wild arms 1. =)

Elite!

Nah, I kid. Flight sims don't do well, especially Wing Commander. I think Ultima 7 is the best of Origin's games that have lasted. Sure, the perspective is really peculiar, but the aesthetic is purposely timeless and colorful. Too bad the text mars it.

Obviously Squaresoft had some of the best 2D graphics ever produced, and FF6 and Chrono Trigger definitely show that. The inherit grittiness of the style, yet the life it breathes is the pure essence of great aesthetic.

Rare and Insomniac games also do incredibly well, since they pushed the boundaries for the time. Banjo Kazooie is still great fun to oggle at, even with its stretched texture. And how could anyone say that Donkey Kong country is ugly? Retro studios also ups the ante often as well, and I will attest that Metroid Prime looks far better than Halo.

And the winner is.. Commandos

If I talk only about PC games, I'd say most 2D games with SVGA or better (ie. minimum 640x400 or so, with 256 colors or more).

VGA games are a borderline case, I find many of them a bit painful to watch nowadays, pixely mess. But that's ok as long as it doesn't affect playability, like the awful pixely fonts in Darklands that were even a bit hard for me to read (IIRC).

For 3D or FPV games, it's a bit hard to say. I don't care that much for Doom or Duke3D engine games anymore. For polygon based games, depends, as long as they run at 640x480 or up, and are 3D accelerated. I was e.g. surprised that I didn't find the graphics in Tomb Raider 1 (3Dfx accelerated) that bad, they still manage to make me feel like I am really being there, and Lara's ass still looks voluptuous.

The main thing that seems to catch my attention in old 3D polygon games is the low texture detail, e.g. all the textures in Tomb Raider 1 or Half-life 1 look like fuzzy mess, more so that I really remembered. But beyond that I'm fine.

Anything 2D stands up fine, looks like art.

Anything 3D since around 2000 looks fine to me now, the Xbox era and beyond on consoles I guess. The in-between stuff looks fucking terrible and I barely ever replay those games for that reason.

Everything after ca. 92 looks just fine to me, most games before that have 16 colors graphics or less and usually look like shit. Games like Prince of Persia are an aversion, since their color palette isn't randomly splattered all over the screen.

Heroes of Might and Magic 3

I've seen some shitty 2d, but in general I agree.
