TL;DR
In the new game screen you can select the island map type. But, its a single island on a very very big mapWhat ?
I suggest a islands map type is implemented that would generate other land masses around the starting island. That way you have to fight for the resources and the other islands with the biters.Pictures
Yes there is a mod for it(Singular that is actually working)
, and while the mod is great and all it isn't perfect. And i also believe that the vanilla game would benefit from this.
