Hey guys, while setting up a single player world to test something out I generated this world which spawns you on a large island that is completely cut off from a mainland. The only land visible from the island is another smaller island from which you can then get to a much larger continent.
I remember someone mentioning a while ago that they were interested in setting up a civilisation and I have done it with a class last year, it works really well. This is a large island that would suit a class of 30 students because there is plenty of space to build.
