I have to disagree here. In my opinion LFS has very strong community compared how long it's been without major updates. It's just that no one wants to drive 5 years same tracks and cars. Now recently there has come the "limit". No updates in a long time and lots of other simulators have been released. No doubt there will leave people to other games. It's not community's fault that there is "better" games in market.
For me LFS is still the best racing simulator on the market. It's just that not everyone think like that. And you can't really blame them. In my opinion it's stupid to use words like "weak community" to game which has been 7 years without updating their content.
