    Not sure if it has anything to do with playing games on windows... but
    after awhile , the power brick gets so hot , that u can hardly touch it..
    I mean , I played on bed, so i put the power brick on a mini plastic lap desk for being a paranoid freak from accidental fires :) , because of the heat , the power brick twisted the plastic of the lap desk surface...

    is this heat normal or should I go to the nearest apple store ?


    *edit*
    I bought the macbook pro retina in the states and now using it in israel where the voltage is higher like 220v instead of 110v in the states.
    just adding some info

    Doing anything intensive on a 15-17-inch MacBook Pro will cause the power brick to heat up dramatically. Remember, it's only 85W. A quad-core i7 and discreet GPU alone will get close to that number, and that's not taking into account driving the LCD and other components. Nothing you can do about it except not have the power brick sitting on a bed if you're going to be doing something that requires full system power. Razer and HP have figured out how to do slim 120W AC adapters. The 2012 MacBook Pro launch would have been a perfect time to introduce a redesigned line of adapters. Actually, that's something that should have been done last year. Apple dropped the ball then, as they have now.

    guess that sort of calmed me down :)
    though i had a razer blade 5 months ago and when it comes to heat ( laptop wise) macbook is allot less warmer, so if its either a hot machine or a hot power brick , i would rather go for the cooler laptop... one of 3 reasons i sold my razer blade right away was that I felt 80-90c on my legs when playing in bed. so far the rMBP been nothing but perfect.

    Mine gets hot too... very hot. I noticed that the heat gets better if you don't use the extension cable and only use the little prong that is built in. I have found the rMBP to be a bit of a space heater in general though...
