How do you play on minecraft with a world you create instead of a server?
The big button on the home screen that says 'Single player'
Well on muiltiplayer. That should be pretty obvise with the title
Not really obvious at all.
Uh, to play with friends on a server on a world that you want, you need to open up your own server. Google on how to do it. You'll need good internet and quite a bit of computer RAM. Unless, you want to pay for hosting.
