If you thought this was too good a deal to be true, I guess Microsoft agreed. A short excerpt:
"You can no longer claim a trial of Xbox Game Pass for £1/$1, just days ahead of Starfield, the year’s biggest Microsoft launch.
“The option has been removed from Microsoft’s Xbox Game Pass sign-up website (thanks, XGP). Now, you must simply pay the full amount for your first month.”
Yeah my dad only ever plays one game at a time so I can definitely see him setting aside a whole month for starfield if he gets it
