Ok.
No amount of mental gymnastics can paint anything different than what MS said internally. They even knew damned well before even launching the service.
Games don’t sell more that appear on it. They even admitted they lose sales. Argue with them.
There no contention that the raw number of units sold would likely be higher if it was exclusively only available through traditional buying.
There’s no mental gymnastics, I’m simply saying the article you posted is not Microsoft saying you end up with more units sold than if you didn’t have it on gamepass. But that there is additional sales that arguably would not have happened if the game was less accessible. And that those additional sales help for an overall healthy business model for them.
If you look at the quote in context, He’s not championing it as the best most lucrative model or that it doesn’t canibalize sales. The fact that it canibalizes sales is implied in the question which Spencer just says he’ll just say the model has been healthy for their franchises then brings up this positive effect increased access has in that quote from the article. He’s not even saying it will work for all games either but that it’s been healthy (not great) for them and that 3rd party should make their own business decision but he thinks that it’s a good option.
The concept of the positive effect is this:
If A, B, C, D, E buy a game if store only
Then A buys game only if on gamepass but B, C, D, E + F, G, H, I use gamepass
Because game is popular/trending/hyped J or even K might possibly buy the game. It’s obvious that gamepass canibalizes the sales of B, C, D, E because they literally aren’t buying it but the concept is that there is potentially
more additional people (J/K) that end up buying the game due to so many people talking about it.
