Well, it just says they’re including it with Game Pass. So you have the option of not actually purchasing the game for $70 (every year!) but you still get to play. There’s a lot of good games for both Xbox and PC so it’s a decent value proposition for a lot of people.
I don’t buy AAA games, so it’s kind of nice to have the option to play some of them without a big upfront investment. The real stars are the smaller and indie games.
It’s not for everyone, but for the cost of a Netflix subscription I can play a shitload of games on my PC and my kids get a huge library on the console.
This is why I like GamePass. There's a bunch of games on there that I probably wouldn't play otherwise. And yeah, they're not all great, but I've found some that I really enjoy.
Maybe you're thinking of Xbox All-access, which allowed users to buy Xbox + Game Pass Ultimate and pay them all over one year (or three, can't remember).
Buy Xbox and then either subscribe to gamepass ultimate or buy the game and then subscribe to gamepass core (just renamed XBL gold) to play online. Its still dumb that you have to pay to play online but you still have the option to outright buy any MS published games.
Now those online services are supported by digital sales, like on PC storefronts. Digital makes up the majority of console purchases now too, but they still continue to charge for online, so it's no wonder PC market share grew in the interim.
