Help please!!Will gamestop sell a mature game to a 13 year old with a parent?
The policy is to not sell a mature rated game to anyone under 17 UNLESS they have a parent or guardian give permission. In practice the person working there will ask your dad if it is ok to sell it to you, if your dad says yes than that's that.
