DS turns 6 next week and he is desperate to play minecraft. We are thinking of downloading it for his birthday. Unfortunately for him his parents are a bit out of touch with popular culture. We are not a gaming family, we don't have xbox or a PS so it would be on the ipad. Where do we start?!! What version is suitable for a keen but unsavvy computing 6 year old? Are there any books/tutorials you'd recommend - to help both us and him? Thanks!
