Nothing could be worse than the Virtual Boy.
The N64 was a bigger let-down because Nintendo had all the momentum from the success of the SNES, and went in a completely different direction. It seemed the only thing they cared about with the N64 was FPS's and 'Me too' 3D platformers, and a majority of the time sucked terribly! Where were all the great action games/ Fighters / RPG's/ shmups/ Side scrollers/ METROID games that made the SNES so excellent?
And as for the Virtual Boy it basically had NOTHING to live up to as it wasn't a sequel to any of Nintendo's systems or a next gen system, it was an idea that was going in a completely different direction. It never caught on, but I can still have fun playing my Panic Bomber on it!!
And besides with the new Wii Virtual Boy 2 on its way, its time to except this system as a cool idea that was far too ahead of its time!
