Honestly, I'm not sure a market exists for them now. With PS and Microsoft already having their own online stores where you can buy and download any game, including pre-ordering and early access for doing so. Gamestop is kind of in a bad spot. Brick and mortar businesses like Gamestop are losing more and more of their customer base to the online stores. Especially with both PS and Microsoft now offering subscription services as well where you get "free" access to a library of older games that Gamestops business was built on selling.
I honestly see no business model or redesign that saves Gamestop. And neither did all of the short sellers currently losing their asses on their stock right now.
I think they’d have to get out of retail completely, and quickly pivot into content creating. How much cash they have on hand and what it would realistically cost to acquire smaller creators to build a viable library soon enough, I honestly don’t know. At least this whole episode has boosted their brand for the time being, and maybe provided enough of a window to pull it off. *shrug*
