We've just got confirmation from the creators of Myst, the mega popular computer game from the 90s, that Disney did indeed plan on turning Discovery Island into a Myst theme park.
If you're not familiar with Myst, it's a game where you get to adventure around the magical island of Myst, to solve puzzles and uncover secrets. It was massively popular, and was the most sold PC game until it was dethroned by the Sims in 2002.
It was long rumor that Disney had planned on creating a theme park, based on the hit game, and in an interview with the A.V. Club Myst creator Rand Miller established the validity of the rumors saying "That was absolutely true. At some point, there were some really cool plans to do some stuff with Disney, we were looking at is as the ultimate incarnation of our world.
He went on to say, "Their Imagineering team was excited about embracing that and building some stuff into it and tying it into the rest of the park where you could explore and have this real world experience. But the way Disney works and the way it had to fit in with their bigger scheme of things, and the way we didn't understand pieces of it, I think it fell apart from their point of view."
And so, we don't know exactly why the plan was never put into action. But now that we know it was a possibility, we would love to see this brought to life!
