There are many trees, animals, resorces, mining space, ect. in the play world... If you look at live map you can see that many parts of the play is open and not build on. Also you dont have to walk that far to find a place to build. When I 1st started play world spawn and houses scartered all over the play looked exactly the same as it did now, even though it was 3 1/2 months ago and it took me only 10 mins to find a non touched forest, desert, jungle, ect. and it still the say now. Hasnt changed, but opening new parts of the play world up is a good idea so there is more to explore.
