I'll first try the demo before buying anything and honestly, since Victor announced that the new tyre model dramatically improves the feeling in LFS, I don't really see a apparent reason to buy nK, other than out of principle to support the lone-developers, of course.
I know nK will be alot better than any of that ISI rubbish, but pre-ordering it is far from being a no-brainer, unlike S3 is/was.
Anyhow, demo will tell...
