Those worlds woud be prety dangerous and I doubt if anyone woud have a chance to enjoy them as you woud die within a day or entering them. or they woud be quite emty and boring since everyone is already dead.

I have similar fantasy except that everyone in this word is pretty much immortal and wea ll have acces to most advanced technology. this allows everyone to enjoy all that anarchy in full extent.
this woud be world of never ending chaos and freedom. nobody could hold their position for long everyone woud be temporarily taking over and goning down then going up again.

I think futurama is good example of that kind of world.
