Yes, the 3DO. I owned one, due to a series of weird circumstances. The best thing is that it came with good games (that my father picked somewhat at random, he never knew much about videogames), especially Star Control 2. The fully voiced encounters were incredible, as was the sense of exploring space.
BTW, although there was a PC version of Star Control 2 before the 3DO version, it had poorer graphics and didn't have voice, so people ported the 3DO version for the PC some years ago. I replayed it again last year, and it still is a great game. The PC port of the 3DO version is known as The Ur-Quan Masters [http://sc2.sourceforge.net/].
Also, Gex and Road Rash. I had played Road Rash on the Genesis, but the 3DO version had a cool soundtrack [http://www.youtube.com/watch?v=QlfrJDglTMQ].
All in all, it was a good system to have between the Genesis and the Playstation, which I only did get sometime after launch and some price drops.
