So, Minecraft is an exploring game and there are two modes: Creative, you have every resource in the game, you don"t die and you can dig or mine at a rapid speed with your fists. Survival, You have ten hearts and 10 hunger points and the goal is to survive. There are no levels but you can adjust the difficulty. You start off with nothing and usually in the beginning of the game you mine wood for resources and tools, or kill animals for food. Now I will summarize some of the more advanced details. Once you have enough wood, you can make a crafting table and it will craft stuff instantly for you, and you can make tools, armour, blocks, potions etc. Once you think you are pretty well off, you can go into a cave and look for resources to make armour and better tools. The challenge in minecraft though is that it doesn't stay day forever (unless you turn off daylight cycle but then you wouldn't earn achievements) and at night the monsters spawn. Just to clear up any questions, yes this game is child friendly and it wont scare your child unless he has the volume at max, in which case the zombie moans would be very loud (lol) . Yes I know that still sounds scary but the game is animated. Some of the basic monsters are: Spiders, Skeletons, Zombies, Creepers (Failed attempt to code a pig, not joking) and Witches (and some others you've never heard of).
