I only have one question for this. Once the game is out on PC, is there a possibility of porting worlds between PC and Xbox?
Chances are someone within this community has the technical skill to do such a thing. We can only hope and wait for a tutorial by them.
Though I think it would work going from xbox --> PC, not PC --> xbox if the PC is capable of making better worlds, more items and blocks, etc.
I for one would like to be able to port my old worlds around, whether it be possible via an in-game port (not quite sure that is possible, but that's for a developer to tell), or via more "shadey" options.
