Think about how many people a company looses on their platform between generations or how long it takes to recoup them back. Now with game pass for the more casual gamer who might buy a handful of games a generation MS doesn't have to worry about the switch between generations as much. If you have an xbox one you can paly xbox series x games heck most likely xbox next generation games too , if you have a xbox series you can play next generation games , if you have an xbox streaming stick you can do that too , have an older pc or tablet or cell phone? You can do it also. It just makes sense for microsoft.
It's also great because once you buy into the Microsoft Ecosystem the rock bottom price is the monthly (or yearly ) sub. But you can go as far as you want. You can just subscribe and use your current devices , you can invest in a series s or x for higher quality more consistent couch gaming or you can go balls to the wall with a $1500 video card + $1,000 cpu and $500 motherboard and $500 of ram and $500 of nvme drives and so on and forth on the pc side.
