I received lessons on how to play Minecraft from my granddaughters. You will be amazed how young children learn games and want to share their knowledge with you by teaching you how to play the game with them by explaining characters and objectives in the game.
The game contains violence and can get intense at times when the creepers come after you. The creepers are the bad guys in the game. The game also allows children to tap into their imagination to move objects and create structures letting their imagination loose to be creative.
The right video games can be used as learning tools for your child as long as you keep a balance. Do not let them get consumed in the virtual world reminding them to not just play video games. Read books, play outside with friends and do your homework.
