I'm glad to spend money in a product that is still in development, aslong it works fine without any significant bugs. LFS is definitely such a product.
LFS does his job, it's a online race sim. POINT.
But LFS is more, to. I like the fact, that if I now stop playing and come back after a longer periode, the game has changed. It has developed, it has new content, it is better than before. All without bying a new product. I often stop playing games, cause they normaly get boring after a while. But LFS gives me the option to observe it, thats excitingly and not as boring as other games.
