It is everything correct what you wrote.
The main aspect on the Atari Blockchain Version of "Rollercoaster Tycoon" is the nature of this Game. It is a Game where you create your own world and the many attractions. Everytime you create your own Rollercoaster or a Park it is a unique thing. But only playable for yourself and not for other people.
With the Blockchain you can now sell it or trade these custom items to other people.
The Custom Designs would be called a "Non-Fungible-Token" on the Blockchain.
