The "prices drop like a rock" thing isn't really true anymore since the PS5 generation began. Prices are steady now. You can still get some good deals if you buy physical media.
But the price isn't really an issue. Cheaper games like Housemarque's Alienation, Matterfall and Nex Machina all flopped.
Cheaper japanese games like rain, or the latest LocoRoco and Patapon games all flopped. Even bigger games like the latest Everybody's Golf flopped.
You already get a massive amount of japanese and western AA indie games. So Sony was looking for japanese AAA games and they also flopped. We keep seeing
"I miss Japan Studio and Sony's japanese games" posts everywhere but no one bought these games. People are buying Spider-Man, God of War, Uncharted, Ghost of Tsushima, Horizon Zero Dawn and TLOU. So Sony is making more of them. The days of Shuhei Yoshida's
"We look at our financial results of the titles, and probably three or four out of ten make money, and maybe one or two make all the money to cover the cost of the others titles..." are over. This strategy worked 10 years ago but now even a smaller AAA game like Ratchet & Clank: Rift Apart costs over $80 million.
Sony made games like Patapon, rain, LocoRoco, Gravity Rush, Knack 2, Echochrome, Puppeteer, Afrika, The Tomorrow Children and more for several console generation. No one bought them. Sony made two VR headsets and dozens of VR games. Almost no one bought them. Sony made a few smaller and really funny PlayLink games. No one bought them. Sony made a powerful handheld with the Vita and no one bought it. And no, the expensive memory card wasn't the only reason why the Vita failed.
People didn't buy Sony's smaller games, so Sony stopped making them.
People didn't buy Japan Studio's games, so Sony stopped making these games and closed the studio.
People didn't buy the latest PS VR2 headset, so Sony will stop making more of them.
People didn't buy the Vita, so Sony (and even Nintendo after the 3DS' rough start) stopped making handhelds.
People didn't buy Sony's JRPGs, so Sony stopped making more JRPGs.
The people decide. If you stop buying Sony's singleplayer games, Sony will stop making them.
If you stop buying Sony's multiplayer/live-service games, Sony will stop making them.
If you stop buying VR headsets, Sony and Meta are going to stop making them.
If you stop buying consoles, Sony, Nintendo and Microsoft are going to stop making them.
Put your money where your mouth is.
