Not at all. When playing on xbox you dont render the whole world so playing on a server would be fine. It would take a small amount of work protocol wise to make the versions sync up but after that you should be good to go. It would be a similar story on phones although there would probably be heavy lag cuz phones are badSurely it will be impossible to put the map into Xbox and Play Station because our map is way bigger than the size of the worlds in both consoles and versions.
