No it was their mistake. Not strengthening their multiplayer portfolio was the dumbest thing Andrew and Co did. Their lack of foresight is now biting PS in the ass. Pursuing multiplayer games doesn't need to be at the detriment of their single player games.
Nintendo does both. Microsoft is now doing both. Sony can do both
Ask those fortnite players what other games they play, probably very little, or none, no point going after those players with 10 different gas games, u got now 17m ps5 sold, lets assume sony gets lucky and gets 1 out of the 10 gaas they making succesfull, that means cash/time which could be spent on multiple single player games by its playerbase will be spent on that 1 gaas game, total waste, same of dev team/pubs money.
Players time and cash arent infinite resources, some1 who plays 5h of fortnite every day wont be buying 70$ AAA game every month, or even every 3 months, i know my casual friends that play csgo, fortnite, warzone and apex, its not even 4 of those at the same time, its 1 each for each person, no other games, coz they dont have any time to play other games, no need to spend cash on buying them.
The tactic jimbo has taken is 100% wrong aproach, it wil lead to much lower game sales, just like on xbox, and sony isnt microsoft where their games/xbox division can ride on the succes of whole company, if playstation division fails there wont be anything to fall back on.
And yup im positive those bethesda+activision/blizz money MS spent is more than any profit(net profit, not revenue) their games/xbox division made whole time it excisted- thats how bad it was/is.
