Super mature... yet you spelled the (da), laugh (laff) and me (m3) wrong. Being mature has nothing to do with being able to play certain games over others. I'm going to assume you think that since you can play mature games that it would seem childish or nerdy to play a game like pokemon, well I'll just tell you that I'm 14 going to be 15 and I'm perfectly fine with wanting to play pokemon. Hell when I went to pick up gta 5, I pre ordered pokemon x that same day. The cashier was pretty chill about it so I'm pretty sure he was going to play it as well. Remember most people who work at gamestop do play games themselves aswell so I doubt they'd care what you play.
