I agree with Greboth. The game community, gameplay, physics, skin, tracks and other is mod-able and also the graffic etc. is improved time to time!
I'm playing for about 1 year now, and I won't stop playing LFS until I feel someday there is the right time I should stop & goes on with my own life...
Currently, I will keep playing till i'm 20 and so on...currently i'm 14..
