Not sure this rhetoric of less SP is coming from. Are studios like Sucker Punch broken up and not working on anything? We don’t have any announcement, but it doesn’t mean it doesn’t exist.
The live service stuff sucks, but once it all comes tumbling down - which is almost as sure as a bear shitting in the wood - lessons will be learnt. Even despite this, these games are not replacing the SP, they are side by side.
I feel no remorse.
It's not so much less SP games, but potentially less marquee AAA SP games because budgets continue to increase along with inflation year over year, yet the amount of funds Sony are putting towards traditional games for the next 3 FYs is relatively stagnant. Meanwhile, funds towards non-traditional games will skyrocket.
Possibility we may get MORE SP games but only IF Sony finally started making and/or funding more mid-to-high scale AA games, at least some with legacy IP, that could be SP-centric. While that may drop the amount of AAA releases down for a couple years, actual volume of games would increase and there's no reason the AA stuff can't be to the same level of polish and fun as the AAA stuff. And with much smaller budgets per game, would allow for even more creative risks and design styles.
I still think PS3/early PS4-era Sony got the mix of this right. They had the AAA stuff like the Uncharted games, Killzone, GT, Heavy Rain, Resistance, TLOU etc. but also smaller and non-cinematic stuff like Fat Princess, Echochrome, Puppeteer, Locoroco, LBP, Motorstorm, Wipeout and so on. Some were even MP games or had MP modes to them.
Even if they have to partner with 3P devs to make it happen, it would be good if Sony could re-establish that balance again with traditional non-MP centric games.
