After 30+ years of gaming (and development, some in games), I’ve known many worse games.
You only have to zoom out a little to appreciate that this version of MSFS is the best in its 40 year history.
Sure, it has issues, it’s a complex amalgamatiom of software services and components.
It can’t not have issues. If they get to the point they make you scream, it’s time to take a break and play something else.
There are many many ways to use msfs that don’t require AI GA traffic, and attaching your satisfaction of the sim to elements that are well known to not work for now (such as AI GA Traffic) isn’t a good lifestyle choice. They know about, they’re working on it, it’ll be in one day, just don’t hold your breath on it, it’ll be in when it’s in. Or perhaps a robust 3rd party solution will appear (or one of the existing ones will mature to that point). Either way, that’s not likely to happen until they finish the ATC refactor/rework as that is an essential piece of the puzzle for AI GA traffic to work, and that has some time to go until completion.
Just enjoy it for what it is now.
Change your perspective, breathe easier.
