I am guessing that it will work in a similar way to terraria, but just asking: Will you be able to play with two different characters on the same world? Will character and world save files be separate? Will it be easy to download/upload world and characters? Can you easily convert an existing SP world into an MP world? How would this be done? It would be cool if you could just make a world into a small server in one click
Ok: Ok in order: Yes, same as 1., depends on a lot things(not sure) , SP and MP worlds shiud be the same so no cinvertation needed.
maybe there would only be one world but you spawn on a different planet that's very far away from the last one .
is there any info about the space travel speed? will it really take some time to fly from planet to planet or do we have a FTL engine?
Except you start in a space station and travel to different planets from there. People need to read this more often.
