They shouldn‘t have added it to GamePass on launch day but wait a few weeks or even months to stretch out the server load.
I bet there are tons of causal and first time players that are already subscribed to gamepass that wanted to try out MSFS24 just because they have access to it. Now those people are pissed off even though they would have waited longer to get a better experience.
Makes you wonder if they are price gouging and withholding innovations behind the scenes. It’s a duopoly nonetheless.
