My DCs (9 and 7) are utterly obsessed with Minecraft (has been Angry Birds and all sorts of stuff in the past). I am rather old school and tend to be quite sniffy about endless time spent on screens. I had some pointless fantasy that they would spend the summer holidays being creative, climbing trees, inventing plays, blah blah. Yeah, right. Anyway, in my experience whenever I cave in allow them to play this wretched game they turn into highly-strung addicts. It's almost impossible to get them off it - I have to drag it out of their hands - and they tend to be in a vile mood for a good while afterwards. I really RESENT the fact that the whole thing forces me into the role of some harridan saying 'no' the whole time, but if I left them to their own devices they would just stay in darkened bedrooms all day glued to screens. Wondering how other parents handle this. How much time is too much, for starters.
