Might just have to have a go at this demo. I have never really given X-plane any serious thought until now as with having so many FS9 addons (and $$$$$ spent) I really couldn't be bothered. FSX is too troublesome and in most respects too cartoonish for me to treat seriously. If P3D don't go 64 bit then this may be the leading future sim (why don't they show their hand?). All the other sims are ageing yet X-Plane is developing. Outerra shows promise but has a long way to go and will need to court developer interest.
