I understand what you mean. For me, it would be the idea of owning the equipment and being able to play the Laserdisc on a 16-bit computer like the ST.
Since Amiga computers cost a small fortune today, the chances of me buying one (after selling my A1200 in 2003), is slim to none, even though its a little easier to find Michtron’s Journey to the Lair package for the Amiga. In fact, some collectors have sold the Amiga version of Journey to the Lair on eBay in the past, but at extremely high prices. I remember seeing a complete, expanded A500 with the Laserdisc player, the DL Laserdisc, and all cables on eBay, and the auction ended at $12,000USD.
Talk about expensive!
Edit: I could buy a refurbished Dragon’s Lair cabinet for that kind of money.
