I wouldn't take that bet.
If you look a clothes as an example, the big companies Nike, Addidas are actively trying to increase the sales they get directly from their own online presence, squeezing out JDsports, SportsDirect etc. Xbox and PS5 and Steam already have a much better window to directly sell straight to the consumer and to cut out the middle man. The only reason gamestop survived this long is because of second hand sales which is not possible digitally. There's no way MicroSoft or Sony will ever let GameStop turn into a Steam for their consoles.
Fair play to that lad if he's made money but I don't agree GameStop can transform itself, I don't see the opportunity or what it could actually become when the companies you depend on are actively trying to kill you.
But I could be wrong, wouldn't be the first time.
