Does S2 not feel like a finished product to you? It sure as hell does to me.
After each session on LFS I have to remind myself that it's still officially a 'work in progress' and after each patch I seem to be even more impressed. Compare that to sims you pay much more for which are released with multiple bugs which, if they're not fixed in the one and only patch to be released, you have to just live with (GTL anyone?).
With LFS you know, you just KNOW, that a great sim is going to get even better. Waiting for it is easy when the version already released is as good as it is.
So ... patience people. Race on.
