As per the title, the Steam edition of FSx is currently on sale at 7.99, it's normally 19.99, so if you haven't got that version, it's probably woth a go for such a low price.

I got one question: Should I buy FSX Steam Edition, if I also have Prepar3D? 

It would be nice if you could give me some reasons to go for fsx Steam Edition

I use FSX-SE for photoscenery and P3D for Orbx scenery

So in your opinion I should buy fsx se

Only if you need that flexibility...

Cheers

well, for eight quid it's worth a go I would say. Like P3D, the Steam edition of FSx snazzes things up a bit to the extent that I binned off my boxed and download versions of FSx off my drive and now only use the Steam version (and I do also have P3D). Sometimes it can require a bit of manual tweeking to get older FSx add-ons to install into the Steam version, but generally speaking it isn't too hard to do. There is also the fact that FSx-SE is vastly improved on FPS, memory usage, texture usage etc.
