I fly FSX, and I have a powerful computer for it too. However I also play YS Flight. Why ?
Semetimes less is more. I can fire up YS in less than a minute, and be online flying air combat against friends from around the world soon after that. I can often carry out a complete online mission (combat, formation, virtual airline) in less time than it takes to fire up FSX and create a new flight
There are many add-on aircraft and sceneries that make the experience more fun. The game as downloaded is admittedly not too impressive. Howver with mods it becomes a blast.
The lack of texture mapped (skinned) aircraft renders it not as pretty as FSX, but conversely, it is not as demanding of hardware. Quick boot times result in a quick fix of simulation fun. I often just don't have the time to fire up FSX. Other times I do.
In conclusion, I don't claim that YS in any way competes with FSX, I just want you to consider that a lot of fun can be had in a small and free package. Checkout yspilots.com for links to many excellent add-ons.
