Old games that aged well

[Rooster893]

Halo: Combat Evolved will never get old. And the Anniversary Edition is even better!

old school sonic and Mario games. Pokemon games. vector man, comix zone. mortal kombat, starcraft diablo.

Wind Waker. Because of the style it was made in, I doubt that game will ever look bad.

Also the Mega Drive Sonic games.

Mega Man X still looks really good considering its age, frankly so do most mega man games. There is something just graphically right about them that makes them looks great years after they were made.
