A blocky world that is similar to a lego world. In surivival you have to collect materials and build weapons and armor to fight mobs. You also need to build a house for defense. Mobs are like spiders, zombies, skeltons, and creepers are main ones. A creeper is a mob that blows up when you are near it. There are also other diemensions like the Nether and the End. In creative you have unlimited materials, can fly and can turn off mobs. Usually really cool maps are made in creative mode.
