A lot of the “gamer” crowd will move on sooner or later when they get sick of hearing “overspeed overspeed overspeed” while using Xbox controllers. When MSFS first came out it seemed like every gaming YouTube channel and streamer was playing it, but that lasted only a few days. Those people will get sick of stalling out of the sky and crashing into buildings quickly.
My hope is that some of those who started out as gamers will eventually become very interested in the sim hobby and flying in general and in the end it’ll be a net positive. And hopefully with time development will be more focused on the sim aspect to hopefully create the best flight sim software to date.
