Voted but the poll seems to have not recognised it.
I used to have one, my father bought it pretty much when it came out in the UK. It was a pretty revolutionary thing at the time!
The games we had were:
The 7th Guest - which was way more awesome than the PC version on account of it's actual, recorded music playing off the CD instead of the MIDI versions the PC was lumbered with.
One of the Zelda games, can't remember the name but it was the one that featured Zelda herself as the player character. It wasn't a great game by any stretch, but it lived up to the idea of being Nintendo Hard, for sure.
Then some light-gun style shooter, Escape from Cybercity or something. Also pretty hard, from what I remember... but pretty good and very non-linear, for a rail shooter. It was more in the style of, say, Dragon Quest than an actual rail shooter.
My main memories were being overjoyed when - after trying to play Zelda with the horrible joystick built into the standard remote - my father bought the joypad for it, and many family nights clustered around trying to work through the puzzles on The 7th Guest. It also let me explore a lot of the music my father was into via video-CDs - mainly Queen and David Bowie.
Good times!
