The game seems extremely easy. And after you complete it the first time there's no challenge at all IMO. So why's there no adjustable difficulty?
For example when you make a new world you could set a difficulty for it. That way it would be a part of the world's settings and would work just as well in multi-player as in single.
I know there are mods for this, but I'm just curious why this isn't part of the vanilla.
This seems like a very easy thing to do really, hope the devs will add this feature one day.
