The RDI Halcyon - Maybe the Rarest Console Ever

Exhibit A: the RDI Halcyon. Exhibit B: a 2011 Honda Accord V6 EX-L sedan*. One is a very rare video game system. The other includes a GPS navigation system, leather seats, a 271 hp V6 engine, six airbags, and has less than 42,000 miles on it.
They're worth about the same.

Background/History:
The Halcyon was intended to be a system far ahead of its time, an "ultra high end" system. Beginning in the early 1980s, "interactive movie" type games began to be released into arcades. These games allowed the player to make choices that would trigger video clips, with the effect that one game could afford numerous different "movies" depending on the choices made. The concept was much like a "choose your own adventure" type book. The animation in the games took up a lot of space, and required the use of LaserDisc as a storage medium. Sega's Astron Belt, developed in 1982, was the first of these games, but the first successful interactive movie was Dragon's Lair, released in 1983. Dragon's Lair featured movie-quality animation by veteran Disney animator Don Bluth. The game was trial and error based; the player had to choose all choices correctly to finish the game, giving the game replay value. It was expensive to play: at a time when the standard price for an arcade play was 25 cents (59 cents in 2015 dollars), Dragon's Lair cost 50 cents ($1.17 in 2015 dollars). Space Ace, released in 1984, was another successful LaserDisc interactive movie arcade game.
Rick Dyer, who had created the concept for Dragon's Lair and Space Ace, saw an opportunity to bring the interactive movie experience home. Forming a company called "RDI", he began to design a console around RCA's Capacitance Electronic Disc (CED), which was a cheaper alternative. While the video and audio quality on CED was lower than LaserDisc, it would allow the system to be released at a more affordable price. During the Halcyon's design process, RCA dropped the CED program, and RDI was forced to use the LaserDisc. The Halcyon ended up using a LaserDisc player and attached computer. The system had some other never before seen features, including a headset that allowed the player to give the system voice commands.

What Makes It Obscure:
The system cost a stupendous $2,500 when it came out ($5,430 in today's dollars).  In addition to the prohibitive cost, the system was planned for release in January 1985, in the midst of the mid 1980s video game crash. Six games were planned at launch, but only two were ever produced: Thayer's Quest and Raiders vs. Chargers Football. Less than a dozen Halcyon units are known to exist and the value of the system is unknown, but speculated to be in the five figure range. It's possible that a Halcyon, with all hookups and components, could sell for over $20,000.

There is an error on the podcast - near the end, I say "RCA" when I should have said "RDI".
