Hard to believe someone would ask this question and no understanding of why.
I had game pass ultimate for my series X.
Like
@edzieba indicated I dont own any of the games I play.
If I am in the middle of a game (I play infrequently) and they remove it from game pass I lose everything I was working on.
If I stop paying every month I cant play games.
On my steam deck I own everything.
And I can buy my games for pennies on the dollar.
They are mine online and offline.
I can play them at any pace I want without fear of losing access to them or my progress on them.
Subscription model is fine for obsessive gamers that consume games quickly and often then move on to the next "shiny" thing.
For gamers who play less often, want to own their games so they can be played forever, and only pay once; subscriptions are a rip off.
Most younger people dont understand.
A subscription is the "carrot on a string".
The hook to keep you paying.
Just like renting your home.
"You will own nothing and be happy".
