Article fail. Neo Geo, 3DO and Dreamcast weren't failures.
I don't know how the Neo Geo could be considered a failure after dominating a niche for ~14 years and being hugely profitable for arcade operators all over the world.
OK 3DO was pretty close to a failure from the pretty underwhelming games, looking back, but it still had a pretty large library of games which were somewhat relevant at the time. People did buy it and it did get exposure for about a year.
Dreamcast's life was cut short.. everyone knows that, but in its 3 years it still sold more than a number of lesser consoles put together and has at least as many critically acclaimed titles as Gamecube. It was also more successful than the Saturn and the PC-Engine line as a whole and in Japan PCE was more successful than the Mega Drive
The author is forgetting Lynx, Jaguar, CD32, 32X & Game.com.
