Being a collector this is HUGE! I have well over 1000 physical Xbox games in my library starting with the original Xbox. Being able to play them on the current console is definitely a plus!
This system has been implemented (and nerfed) for nearly a year now in the U.S. I've taken advantage of all the possible points that can be earned every day, week and month. You can expect to average around 15,000 points per month! Let's put it this way, I turn in my points every month to redeem for Game Pass Ultimate. Haven't paid any actual money for over a year and have 'banked' points!
