The Duo was: 1) too late, 2) too expensive.
The concept, aesthetics, and pack-ins were brilliant.
The mascot change to Zonk was intended to be more 'badass' looking than Bonk, but I think overall this wasn't such a good idea.
I think I got into this with someone else recently, but Zonk wasn't a mascot change. He looked like Bonk, rhymed with Bonk, was advertised as "Bonk's cousin from the future" or somesuch, and relied on Bonk's name recognition. It was nothing like Sega's changes from Opa Opa to Alex Kidd to Sonic. While Zonk was advertised heavily and featured on the Duo box, TTI never abandoned Bonk - they were busy with two different versions of Bonk 3 and were working on Bonk 4: RPG.
They realized they were marketing the platform to a niche, while the TG16 was trying to be like the NES and have a system in as many American households as possible. The Duo was really more of a "if you are really into video games, this is the hardcore system for you" product. Not to the degree that the Neo-Geo was, but really... that's a whole different business plan.
I disagree. The Duo was very much an attempt to remain competitive in the mainstream 16-bit wars. While the original CD-ROM2 attachment
did initially cater to high-end gamers, technology was catching up by 1992, hucards were starting to look dated, and NEC needed their Super CD games to compete with the new SNES and the upcoming Sega CD. Consumers weren't interested in an unpopular, four-year-old system, an attachment, and an upgrade card, so NEC needed a sleek, all-in-one solution. TTI certainly hyped their fancy media and superior audio, but everyone does that - the SNES box brags about its 32k colors and the Genesis plastered "16-bit" across the deck. As for the price, again, $300 was too much, but I can see TTI's reasoning: it played two different media formats, CD players were still expensive, and it wasn't
that much more than $200 for a SNES.
i could no more swing the $399 then the $250 for the express
The CD-ROM was $399, the Duo was $299.
