I've always said they need to cutback on stores and start having a larger focus on Retro gaming, but the problem with Retro gaming is there's a limited number of stock of said titles, but if they have that (and actually put games in the store, not just have a catalog like they did when I was there) and use their shipping advantage (be able to buy said game from 1 store and get it sent to you or to the store) along with Retro focused clothes, etc. instead of all this random junk they have now.
They can still do the new games, used games, etc. but start actually retrofitting the stores with a Retro focus in parts. Along with their new test stores where you can host tournaments, have systems available for people to play on, etc. There's so much they can do that could get people back in the stores, but they aren't doing them.
I know it will cost jobs which sucks, but downsizing is a must, there are just too many locations. Do fewer locations, but larger locations.
I said all of this to Paul Raines when I had a meeting with him way back when in Vegas when I was a Training Manager for GameStop and he seemed intrigued, but then nothing happened. I left the company not too long after that and left retail.
