IDEA! How about a mod that allows you to go back to the beginning of your world with a portal.
When you start your world the game should save a copy of that seed. Then once you've progressed far enough you can go back to the beginning, but with everything in your original world. So you can go back and forward, and reclaim diamonds and treasures in the world that you already have. You could make special blocks like this:
= Fuel intake portal frame
But you would need the ETERNAL fuel source:
= Eternal Fuel Source
Of course those are buckets of lava not real lava. Each of them would be put into the Fuel intake portal frame thingy and then YOUR OFF! And once you've set up your house in both worlds, block by block your constantly zipping back and forth as you please.
(incase you didn't get that heres the fast version: theres a thing that makes you go back in time, but not really because you wont be there its just the world with a way back to what you had before, like a connection between two worlds so you can transfer items)
so what you want is actully a parallel universe where you never existed?
yeah pretty much, but not parallel, just the same without you,but with you at the same time. kinda hard to explain. think of it this way. Your the only human. its like coming out of a portal to your spawn point as if you just generated the world. but with a way back
yes a parallel universe where do never existed... except you now do because you have gone to it ... yes its possible
you can do it easy on servers... not sure how hard for single player thoill maybe try it later (if i can be bothered that is :tongue.gif:)
