Looking to unload your unwanted gaming gear? You're probably on your way to GameStop. As the largest dedicated video game retailer in the world, it's hard to imagine a games enthusiast who hasn't browsed its wares a time or two. Over the last few years, however, the firm has been expanding outside of retail sales -- dipping its fingers into digital distribution, streaming and even phones and tablets. The brick-and-mortar store even seemed to be flirting with building a mobile network. With all these changes underfoot and a new console cycle just around the corner, it seemed like a good time to catch up with GameStop CEO Paul Raines to get some perspective.
