I think the saturn looks horrible. It's just a big black box. The xbox had at least some color and shape added to it.
The dreamcast is ugly too. It looks like one of those hand dryers in a public toilet.
I like the look of the game cube. It doesn't look like a toy, but it still looks playful. It doesn't matter what color it is.
The 32X looks pretty cool too. Too bad it has to be stuck on top of an ugly megadrive/genesis.
I like the looks of the ps2 as well. It looks really cool and high-tech with the blue light.
