My 7 year old son is desperate to get Minecraft for his 8th birthday. All of his friends have it and he has seen them play it occasionally so is very keen to have it at home. I am a bit hesitant as his friends get really upset when the game is turned off and talk about Minecraft a lot. It seems a bit addictive to me - more so than the games my son already plays such as FIFA and Animal Crossing. Should I be concerned or am I over-thinking this? Is minecraft particularly addictive or just like any other video game?
