out of the ones ive played only.
game gear: shouldn't be on the list. It was awesome. its flaw was that it ate through the batteries like crazy.
2nd worst
virtual boy: was uncomfortable to use, lack of software, lack of quality software, everything composed of black and red. on a positive note the controller was good.
worst
3do: Cost more than a ps3 at launch (it costed $700 at launch and that much money in 1993 was more than it is now). The horribleness that was interactive real-motion video games (sega cd had the same issue)
