This is simple mathematics, no need to obfuscate things. Are you really saying that most of Xbox's revenue minus revenue gained from PC, a total of $14B-$15B, comes from PlayStation as opposed to royalties from sales on their platform, Game Pass and hardware sales? Come on man. Maybe you are the one who needs to face reality. If that were true it'd make Xbox PlayStation's biggest 3rd party partner by far. Keep in mind Activision, who is actually PS's biggest 3rd party partner, has a total annual revenue of around $8B which comes from a combination of mobile, PC, PS and Xbox.
