Bob,
you're right in that, msfs isn't a flying game to us,
but you have to remember, to anyone not simming, it is.
Flight sim is now more than 25 years old,
and by official sources, fsx was a succes, so I don't think ms will completely stop the series.
If they did, they'd loose millions in profit on possible future fs versions.
And considering they're a commercial company, now firing thousands of people for financial reasons, I think they know that.
I to am worried about the future of msfs, but i don't think it's all over, just because of the closing of ACES studios.
