It has to be said, streaming content on this scale was not ready for primetime. Being able to select which content to download to your local PC is a good way to let folks see what they were missing without swamping the boat.
For those with the storage capacity and fast internal access to it, having the entire sim installed removes the impact of downed internet service and overloaded MS servers entirely. That is a win for us.
For MS, being able to scale back their streaming services and commit those resources elsewhere is a win for them. Having that happen gradually rather than suddenly is helpful as well.
THIS finally, is a huge step forward for MSFS2024, bugs notwithstanding.
