Hmm interesting reads. We have to go back 10-15 to reference any of them, but interesting.
Sega Saturn was only considered a launch failure in North America, and is primarily linked to Sega's surprise launch fiasco that released the system earlier than they had announced, and severely limiting the available launch title. A gamble that didn't pay off.
The 3DO launched at $700 in *1993* and management refused to lower the price. Another gamble that didn't pay off.
Atari Jaguar had no support from the upper management at Atari, resulting in high prices and little software support. We all know Atari never had a good run of *anything*. Another gamble.
NGage and Gizmodo definitely fit the bill tho, but coming from companies with zero experience it's not surprising. We're starting to see the same thing today with the Ouya. (granted the kickstarter funders got what they paid for so... Not technically a fail?)
Virtual boy definitely was an all around failure.
I don't think it's fair to lump peripherals into the debate, as none of the systems they were designed for were failures themselves. It's the same debate calling the kinect a failure.
So in reality what we have for launch failures are in fact systems that had terrible lifespans overall. Terrible management support, and terrible software support. Nothing in the last 3 generations has suffered these problems. Everything today is hardware malfunction. Most of the people today crying "launch failure" on the internet were barely alive the last time there was in fact a mainstream failure.
Very interesting numbers. I had no idea some of those systems sold so poorly over their lifespans.
