There are good games on every console and handheld, but as a percentage, which consoles/handhelds do you believe have the highest and lowest concentrations?

A better way to think of it is, if you had a complete collection of every console/handheld and every game, and you were to draw a random game from each of the system's libraries, which ones would most likely net you a good (or bad) game?

Rule: The console/handheld must have at least 10 game releases.

Here's my thinking, in no particular order:

Highest:
SNES
Dreamcast
Colecovision

Lowest:
Jaguar
CD-i
Wii
