If you mean GAF Xbox fans have been wrong, then you would be right. Let's just go over a few off the top of my head.
Power Gap
Series X Crushing in DF Comparisons
Series S Being a Bright Move
Halo Infinite Turning Things Around
Bethesda Purchase Being A Huge Boost To Xbox
Redfall Turning Things Around
Starfield Being GOTG/Turning Things Around
GamePass Being A Huge Success/The Future
GamePass Helping Game Sales
ABK Purchase Being A Huge Boost To Xbox
Xbox Exclusives Not Coming To PS5
Xbox Not Going Full 3rd Party (Pending)
It's funny how neutral gamers and PS fans have been more accurate about Xbox than their actual diehard fans. I guess that's what happens when you actually look at the signs around you and not believe whatever PR your fave company feeds you, regardless of how many times they have lied.
