Lack of advertising and its business model of the hardware basically being produced by licensees tacked on to other electronics products of the time ended up crippling consumer awareness, and the price point was the big nail in the coffin, at roughly $700 in the early 90s you really had to commit to wanting one. Unlike most other console companies, 3DO couldn’t afford to sell the hardware at a loss because they didn’t have much, if anything, for first party games to make up for it. It had some games that look like they’d be decent, at least a better quality library overall than arguably the Jaguar and definitely the CDi, but it’s that tough cycle in gaming where you need good games to sell consoles (especially at $700, in any time) but third party devs won’t make good games for consoles that don’t sell.
