I was thinking, since they are already brick and mortar....
A place where you go to game with other humans.
They can still sell games and consoles, but hire staff that organize the gaming at the store so people either buy a subscription to keep coming back, or decide to buy stuff to take home.
Expand into PC gaming more... partner with Newegg/Amazon....
Sell gaming, not just cold physical copies of games.
Oh and use excess compute capacity of the equipment at each store to mine cryptocurrency.
Even if you have slow days, the store is still making some kind of money.
Yeah...I could see something like that working on subscriptions and/or appointments. Like schedule your chair/headset/system/game dream...and you arrive for your hour with everything set up for a trial. Pay $20 for the hour, maybe each store has 8 stations, fee waived if you buy anything...and you get to try the latest coolest stuff like a sharper image but immersive experience...
host buy-in tournaments. facilitate networking. (almost pool hall like)
play-off against other stores in other cities live as groups (modern arcade like)
Sell Bobo and energy drinks.
Get a liquor license.
Have a "dark" adult booth, for the adult turn in gaming...
and gloryholes and hookers as prostitution is legalized regionally. (stripclub like transformation of the old storage areas)
Sell cars off of simulators, and train for your pilots license as we all might need to operate our drone like heli's, future rides.
Bobo and a blow? $59 combo special.
(I've just realized Idiocracy already did this with Starbucks)
