You know GamePass will cost you more in the end right? A rental service where if subbed for the whole year will cost you $120, where owning a game will cost you $60 (depending where you are from)
$120 x 5 years = $600. Thats the price of a console. Now if you continue paying after 5 years, that will continue to add up to the point it will just be cheaper buying the console and said games you are interested in.
Thats the point of GamePass, like a phone plan, its made to look cheap on the surface however it will catch up to you in the end.
So far I paid $1 to play FH4, Gears 4 and Crackdown. When there is more I can always get it for another month. You can simply make a new account and get it for a dollar again. I have no intention to subscribe for longer than it takes to play one of the exclusives
