Lots of 2D games.

Last gen - Resident Evil 4, The Legend of Zelda: The Wind Waker, Okami, Shadows of the Colossus and Jet Set Radio.

Though for me, I generally find that most 16-Bit console games are still very playable (to this day) and hold up well visually.. Much more than lets say, the majority of older 3D titles from 5th and 6th gen.

Agreed. The 5th gen has aged really badly compared to the 4th. It's the jagged 3D shapes, they really stick out compared to 2D.

I'll take this:

Over this any day:

Black was incredible for the time it released.

My personal favourite would probably be Suikoden 2 though. Its really easy on the eyes for a PlayStation title.

With FFX/X-2 HD coming out soon i must say the cut scenes in the original are amazing. Also with the possibility of FFXII getting a HD remake i really dont think it needs it, i only want it so i can hopefully play it on Vita

Metroid Prime and F-Zero on the GameCube still look beautiful IMO.

Most SNES and Genesis games such as Sonic, Strider, Super Metroid, Super Mario World 1/2, Phantasy Star, Final Fantasy VI. Still hold up well.

Playstation (and Saturn) games like FF Tactics, Castlevania SOTN, Mega Man X.

Most 6th gen games still look pretty good with some exceptions.

Valkyrie Profile 2 looked amazing at some parts
.Hack/ G.U. 1-3
Final Fantasy IX
Resident evil 2&3

Super Smash brothers Melle . The charter models are still fantastic and some of the most fluid animations I have ever seen. Doom 3 Also

The original Ratchet and Clank trilogy has aged pretty superbly I have to say.
