Which video game entertainment systems have aged the worst?

[KungKras]

Yea, all the early 3D systems like the PSX, N64, 32X, Amiga CD32, 3DO, and especially the Jaguar have all aged horribly.

2D games on the Saturn still looks absolutely brilliant though.
Pre-Atari2600 home consoles like the Fairchild Channel F have also aged terribly.
