Poor Retro Support
There was a time where a lack of retro games wasn’t a problem. This is because GameStop was thought of as the premier and obvious place to buy video games, and its selection was pretty much unrivaled. That is no longer the case. One thing that could have helped the company, would have been the addition of retro games. Sure, these are available as part of the store's online model and some physical locations, but there is already plenty of competition for GameStop if you’re going to have your games shipped to you. Creating a shopping experience for retro games would have had value in an age where streaming and Let’s Plays helps keep old games appealing to all generations of gamers.
