Still think mobile gaming isn’t a big deal? GameStop disagrees. Though they may not be as in-depth or graphically stimulating as console or PC-based games, mobile gaming is accessible to everyone. My grandma can’t play L.A. Noire, but she’s beat every level of Angry Birds. So it only makes sense that GameStop has decided to put a couple new devices on its shelves: the iPod, iPhone, and iPad.
