I had this dream of space engine. And from what I can understand is this. you can approach a back hole, and it takes you to some strange tunnel which takes you to a hub. you can select other tunnels on that hub and it takes yo to a different universe with the entirety procedural. Wanna get back home?selecting earth will take you to the back hoe where you came out from and bring you back home.I thought that its an awesome idea since the possibilities of exploring is endless and replayable.
