People spending more time with fewer games is not a reason, in publishers' minds, to reverse course. It's the intended outcome.
Having the same number of people (or near the same number) playing fewer games, and filling those games with monetization features is cheaper and easier to maintain than having a broad and growing library of titles.
Remember, the ideal for publishers is to have one game that everyone plays that has no content outside of a "spend money" button that players hit over and over again. That's the cheapest product they can put out, and it gives them all the money. They're all seeking everything-for-nothing relationships with customers.
This is especially true of publicly traded companies.
A publicly traded company's customers are it's investors, and it's product is shareholder value. Everything else they do is just the manufacturing process.
That's just the system. This is what happens when people confuse commerce with capitalism: They think that capitalism is being rewarded for doing commerce better. Instead, capitalism is about leveraging ownership of property and underpaying workers in order to get money for free.
And the thing about money is that it's really just a proxy for power. When you only have enough of it to eek out a comfortable life (or less), you don't really notice, because all of your power goes in to achieving or maintaining that acceptably good life (or hanging on for dear life trying to survive), but once your needs are comfortably and handidly met, money is entirely about being able to make other people do whatever you want. And the more money you have, the more things you can get them to do, or the more of them that you can get to do what you want.
And if you've managed to be one of the lucky ones who just get free money for owning shit, then you have the power at your fingertips to try to grow your power over others exponentially, while still doing no honest work in your days. And if you're a shitty person who gets off on all of this, that's exactly what you'll do.
The wealthy are insufferably greedy leeching assholes because one does not become wealthy without being greedy, leeching off of others, and being an insufferable asshole.
Unity: Successfully implemented a product strategy that floods the market with game developers that know how to use its product.
You, an insufferable prick: "Why would they use a product they could find ready-trained developers for when they could use a niche product no one has any skills in??!?"
Also, Oblivion just wasn't amazing. It was fine. More than good enough, even. But it was also just unmitigated and completely ubcofused sidequest sprawl. In my attempts to experience all that it had to offer, I ended up feeling like I experienced nothing of value.
Well, you see, the technical issue that's stopping them from selling it is called "canibalization of sales", which is technically an issue for their marketing department.
