I see why this graph is potentially problematic. it's just that without knowing what games sony are working on, i don't think we should be alarmist about it. maybe there is something about live service games where they're just more expensive to make, so that even a modest increase in their production overshadows spending on other types of games. i don't know to what extent sony is counting mlb the show or gran turismo as live service games, or investments in bungie, haven, etc as spending on live service games. Investments in those studios wouldn't mean that santa monica, naughty dog, etc would be making less single player games. I don't know if this data is including third party titles like foamstars, genshin impact, etc. sony is paying for exclusivity, but that has no effect on their first party output at all. there's just a lot of variables. what's really at issue i think is their lack of communication on what games they're making.
but also, i think we're just disagreeing on whether this is actually an issue for sony. i think the lack of ANY major multiplayer games has been a huge problem for sony since the ps3. And it seems like they completely gave up on it during the ps4 era. where microsoft and nintendo make these huge gaas titles, and especially MS is just buying out games that sony used to be able to rely on. they need to make these investments to stay afloat. if MS decides to make COD, overwatch (3?), minecraft, exclusive. what is sony gonna do about it w/ just their lineup of single player games. that's a huge chunk of their audience.
