People like playing games with their friends.
Gaming has always been a social activity.
The biggest thing I remember about classic games like Pac-Man or even back as far as like space invaders, was that you were trying to get a better score than the guy you were gonna pass the sticks too.
Even when we made it to games like Mario bros, it was still kinda about passing the sticks and seeing if your little brothers Luigi could outdoo you.
Going all the way up to GTA3 what did we do??? Sit around with a group of friends and see how much fukkery we could commit before dying and passing the sticks.
It’s only been kinda recently that purely single player games have taken the spotlight. And that’s just cause the people that chose to talk about it online have gravitated to those games.
In reality it’s always been the multiplayer games getting all the attention from the majority of people playing games.

Sony would be silly to continually ignore that market
