Like others, I think the answer to the thread title can be summed up in one word: no.
Imho, the slow pace of development is beginning to have an effect. Both on the community as a whole, and for me personally.
Imho, the fact that we still don't have modelled aero undertrays or engine heat (and thus, radiator damage) is disappointing. When S2 was released in 2005 I can't say I ever thought we'd be half way through 2008 and still not have such things. LFS is also lacking what I call "procedural" features. Like the ability to run a formation lap and have everyone park on the grid, or have a rolling start, or have a dedicated safety car option. The kind of things that aren't so relevant to public racing, but would be huge with league racing, or just more "serious" pick-up servers.
Speaking of a safety car model, the main problem for LFS at the moment, and the reason I can't get back into it properly, is the lack of new content. LFS is absolutely crying for some new tracks. Whilst an RB4 or FZ50 with a lightbar would be handy and novel feature as a safety car (although one that would require some rendering of light sources), what we really need is tracks. I know we're not entitled to any, as we knew what content was included when we bought our S2 licenses, but dammit, I'm so sick of doing the same corners in a variety of configurations. Yes, someone will come along and say, "well there's 8,389 combinations and you haven't mastered any of them". True. Maybe I don't want to "master" them in the sense of running at WR speed. Maybe I want to enjoy racing in a variety of tracks and environments, which is something that LFS is sorely lacking these days.
I really want ot be "into" LFS again, but it's just feeling stale at the moment, I'm afraid.
