Valve was a plucky underdog against the established publishers and, while dominant today, still has reasonable competition, sony is a giant corp with a reputation and a monopoly on playstations.
That's like saying Volkswagen has a monopoly on Volkswagen cars.
Sony clearly does not have a monopoly on the video game industry, and a plurality of video games are cross-platform across consoles, PCs (Windows/Linux), and even MacOS.
But I cannot play 'Astro Bot' on another platform.
Are they not two kinds of games?
I'm arguing that your comparison isn't the right one.
A BMW and a Volkswagen are two types of apples. They both let you drive form A to B.
A Playstation and a Nintendo Switch are two types of oranges. They both provide entertainment in the form of video games.
How you drive (and how enjoyable your drive is) from A to B, or which games you play, are specific characteristics of the hardware you chose to use to accomplish the task. Neither of those are two types of anything, as it were.
But the analogy breakdown because a car is more or less a complete item you buy and use for a purpose (aside from consumables) whereas a playstation is completely useless without games to play on it.
So maybe volkswagen brand gas would be the best analogy here.
Oh, looks like cars and consoles aren't that different after all.
Someone else in the thread made the comparison to fuel, I'll go with that. Last time I checked, there was no such thing as petroleum DRM.
I'm getting a tad lost, though. The point of the sub-thread is that Sony does not have a monopoly over the video game industry. They get to choose which games are allowed on their platform and under what terms. Consoles and Cars both have proprietary components and open interfaces. A console and car have different purposes. And the average consumer has broad discretion to use cars and consoles from whatever manufacturer they wish to.
Sony host a massive, massive marketplace. That's where their monopoly lies, they have end to end control over distribution of not only their games, but anyone else who chooses to publish on the platform, in addition to control over how those games are played and on what hardware.
This hands them an enourmous amount of power over the third parties that make up the majority of software sales on their store. The way they've constructed their ecosystem and services also greatly disincentivises it's users from switching. Games aren't cross-compatible, so buying in for another console means they have to either keep their console (which they could otherwise have sold) or give up their library. Even keeping both means having to choose for one online service over another. These kinds of decisions might not matter to someone over a certain socioeconomic status, but it still matters to many.
I don't think that a market of it's size should legally be allowed to exist. It's exploitative by default and I would be supportive of the EU recognizing Sony as a "Gate Keeper" under the Digital Markets Act and taking appropriate regulatory action.
One can dream.
Until you actually buy one.
Obviously there are levels of wealth where this is all irrelevant, either because buying every console is a relatively minor expense or because you can't afford any console whatsoever, but for the people in the middle where you can more or less afford a console, once you buy into one, you're now kinda stuck with it.
