What is this "rapid change" you speak of? Just saying things are going more multiplayer isn't an answer. Big multiplayer games have been around for decades.
The biggest thing that changes with the games industry is the cost of making top tier software, which continually goes up.
What are the biggest console games lately? Uncharted. God of War. Zelda. Last of Us. Horizon. Grand Theft Auto V (yeesh). The Witcher. Animal Crossing. RDR2.
Notice a theme there? Big single player experiences. Same as back in the NES days. If you think the tastes of players is just going to change on a dime, you are in for disappointment. Or just being wrong. People do not change habits and behaviors, pretty much ever. There is always going to be a lot of demand for this. Yes there is huge demand for multiplayer too, but this idea that the industry and tastes are "rapidly changing" is demonstrably false by just looking at sales numbers.
PUBG sold 60+ million copies on PC/Console. Then it had healthy microtransaction sales. Then there's the whole mobile version too.
Overwatch had 35+ million players in 2017, one year after release. It also had an aggressive MTX model. It's probably done a little more since then.
Rocket League surpassed 40 million players in 2018. It's consistently grown more popular in terms of player count since 2018 according to Stramcharts.
Rainbow Six Siege earned 1.12 Billion according to Ubisoft earlier this year. To put that in context, TLoU2 sold 4 million copies at $60 dollars which earned Sony 240 million. The first time Siege saw a drop in players was in May of 2020. So it's still earning considerably.
Then there's that little indie game called Fortnite which may have broken even by now...
GTAV is essentially a multiplayer focused title at this point. Minecraft is still a monster. As is Roblox, League of Legends etc...
I'm not really seeing single player games being able to compete with that in terms of revenue/sales.
I don't think Sony can look at a supremely talented team like Naughty Dog, which took how many employees 5+ years on TLoU2, and be thrilled with the fact that their games die on the vine so quickly.
The multiplayer, social based gaming revolution is upon us. If Sony is still considered a single player focused company in 3 years, they'll have made a massive mistake.
There is no better marketing mechanic than having your friends talk about playing a multiplayer game in front of you...Sony needs to tap into that.
