In the dream, it was an immersive and highly interactive park with different lands themed around each Dark World. You would build your Dark World weapon (which is how you interact with many elements of the park), and then you were ushered onto an elevator that simulates the drop into the Dark World itself. From there, you would enter Ralsei's Castle Town, which is the central hub of the park. From here, you could access the various other Dark World themed areas through Grand Doors. Or, you could talk to the various Darkners there, and work with other guests to solve puzzles and complete quests. This is also where most of the restaurants are located.

The Card Kingdom area is based on Chapter 1. It contains a dessert vendor based on the Bake Sale, as well as a shop operated by Malius. It also has a kiosk where you can build your own thrash machine, and several rides in the Card Castle, including a Jevil carousel and something involving the King.

The Cyber World area is based on Chapter 2. It has roller coasters, teacup rides, and fireworks shows. You can also visit Spamton in his shop, and try to negotiate deals with him. You can meet Berdly, Noelle, and the Queen as well. There is also an experience where you can pilot the thrash machine, and it will remember the one you built in the Card Kingdom, if applicable.

The TV World area is based on Chapter 3. It mainly has a bunch of games you can play, and quests to do. It's a nice place to relax and have fun after exploring other areas.

And finally, the Sanctuaries, based on Chapter 4. Here, you can explore the Delta Rune Prophecy. As you explore around, you will find various pieces of sheet music. You can play them on various pianos scattered around to discover secrets.

All your progress is saved to your Dark World weapon, so you could bring it back and pick up where you left off on future visits. There is even special security protocol for this, but it should feel seamless. You just tap it to a podium and when it turns green, you're good to go. If it doesn't turn green, you have to leave it behind.

That's pretty much all the ideas I had for now. If something like this were real, I would be all over it. What do you think?
