Me too!

The first game I played with mouse support in the 90s, I believe, was Flight Simulator 3.0, and I think by default (?) it was set up for inverted mouse (or was MS-DOS Star Wars: TIE Fighter, can't remember).

Since then, when I started playing other FPS games with mouse support (like Quake and similar), this mode prevailed.

However, the biggest challenge came years later with FPS games for smartphones - retraining my mind to play with non-inverted orientation. Quite an adventure!
