The other day I was remembering MSFlight and that it hasn't occurred to me to fire it up since the 1st week when I played it about 4 times to see what it was all about.
The truth is it simply did not grab me, hold me or even make me think about it in all this time. I playwed it about 4 times in the 1st 2 days. Then I forgot all about it.
But I have been 'flying' FSX and getting new planes and learning new things almost every week.
What I love about FSX (& previous FS's) is how I can do what I like with it. I add the planes I like. I add the scenery I want to add. It is tweakable to a degree that we are all still learning 5 years after release.
What I like about 'Flight'? I can't really think. Really!
That is an honest and unbiased opinion of a long time Flight Sim user and real pilot.
