Minecraft is a game made up of infinite possibilities. If you can imagine it you can create it.
Minecraft is split into two separate game modes. Creative and Survival. You can play both of them in multiplayer. If you’re mostly interested in making huge structures from scratch with unlimited resources, Creative mode is your best bet. You won’t see any enemies, and you can pull blocks of all shapes and sizes out of thin air. It’s a peaceful world.
However, if you’d prefer to adventure into a world of danger, where you’re crafting and creating out of necessity, you’ll probably want to play in Survival mode. That comes with gangs of monsters who want to break/explode/eat your bones, one pixel at a time. You’ll need to protect yourself from the creatures that come out at night.
Bizarrely repetitive and perilously addictive, isn't it time you got digging?
