LOL. As if 10-year olds even have the money to buy map packs.
It does have a point though and timed-exclusive DLC can make all the difference.
Playing Call of Duty on Xbox Live = $180 including all the DLC.
Playing Call of Duty on PSN = $120 including all the DLC.
If kids going to school can do simple math then maybe more people would play on PSN.
