My first flight simulator was the Sublogic Flight Simulator.
I believe Microsoft later bought that.
3d glasses?

Wikipedia which I despise for anything remotely political has a thorough article on the history of the Microsoft Flight Simulator including its purchase from Bruce Artwick’s Sublogic Corporation.

I have a lot of storage space and throw away very little. I have several versions of the early iterations of this excellent software for various platforms. I was very impressed with the performance I got from the DOS version after I put together an XT compatible desktop computer with an EGA adapter and monitor.
I put together a lot of PC's over the years and the latest Flight Simulator's performance was always a consideration when picking components.
Long before we had high speed internet in our area my neighbor and I ran cat5 cable between our houses so that we could play Microsoft Combat Simulator together. This started a bit of an “arms race” between the two of us where we each purchased higher and higher quality computers, joysticks, control yokes and rudder pedals. I could always tell when he had upgraded his system; suddenly he would be shooting me out of the sky in every game.
