In multiplayer, you can race your friends to beat the ender dragon, eachother, or even simply explore the possibilities.
If you prefer singleplayer, you can beat the end, or expand your base as much as you want, you could build an entire city!
The possibilities are truly endless, you could build a city, beat the ender dragon, fight to the death with your friends, make an entire planet!
One single tree can make you able to do anything you can imagine. You'd better make sure not to drop that sapling.
Version 11.5 is the reccomended version to download, as I'm hopefully not adding any more starting items.
