Make a product, make it good

I hypothesize that if this worked, Xbox would be outselling right now. From a features standpoint, Xbox has been on the ball for years trying to improve their platform. Backwards compatibility, a cheap 1080p console to go along with their 4K flagship, 1440p support from day one of this generation instead of taking nearly two years to put it in, Xbox Adaptive Controller and Copilot for accessibility, Series X|S having Xbox One controller compatibility, replaceable controller batteries so that slow controller death isn't an issue, Microsoft Rewards exists to get stuff like Xbox giftcards for just playing games and typing shit into Bing, a fully-featured Chromium-based browser (meaning you can do pretty much anything on there that you could do on a normal browser, like GeForce Now or browser games like this (and yes, it works with the Xbox controller on the console), Gamepass (specifically Ultimate, which comes with hundreds of games on its own, EA Play Basic, a bunch of stuff for Riot Games games, game streaming, "perks" like game DLC, movies, and trials for services, and more point-gaining opportunities for MS Rewards), and on top of all of that, you can pay $20 for developer access and install emulators for pretty much any console Xbox 360 or below.

On the PlayStation end, they also have a lot of great features, like the DualSense controller (built-in controller microphone is a super nice-to-have, the DualSense haptics are sick as fuck when they get used to the fullest, and they've got gyro functionality for console users wanting to play with gyro aim in competitive shooters), the fancy PS+ guides feature, the most high-end VR headset on the market, and I really appreciate them not using a proprietary expansion format that completely fucks people all the way from launch until like a couple of weeks ago when Seagate exclusivity runs out finally, but that's about where my praise of the platform itself ends (Edit: The monthly PS+ games are also way better than the XBLG games, which is excellent for people who don't want the Netflix-style subscriptions but do pay the online fee).

The real value to people seems to come pretty much just from what games are on the platform. So,

and people pick what they need based on WHAT THEY ACTUALLY NEED.

they actually are. People just wanna be able to play the cool new games, and Xbox hasn't had any in a long time. Starfield might actually be the first game since the Xbox One where a large amount of people are pissed off that it's exclusive to Xbox, whereas PlayStation gets game after game that Xbox gamers would really like to have. Hence, exactly why they bought Bethesda and made Starfield exclusive.
