Yeah, it's a shame
Those were the good old times!
I've been playing Rocket League alot, not exactly a racing game but it filled the gap for me since LFS. Tried iRacing few months back and it wasn't too bad either. pCars and Assetto Corsa were on the list during when it was more active on LFS, but none of those could match the experience back then
Alot various other videogames too, im quite the addict
Still every now and then i'll find myself watching the replays of nice races and putting some good music on the background ^^
