I vote #3 because I LOVE LFS - it's fantastic and has been a constant fixture for about 6 years now, and it has DEFINITELY put real energy behind my love for racing.
The only reason I say I am bored is because EVERY SERVER USES THE SAME TRACKS. It's either Blackwood Hatch/FBM or it's AS NAT with tourers (and that's barely about these days).
If I want good racing with serious players I am forced to stick to these 3 combinations. If you were just going for multiplayer, there's hardly any point in buying the full S2. Nobody bothers with servers that don't have these.
My other gripe is that it's just WRONG that it's possible for someone to go so quick with a mouse and keyboard setup. Someone was posting some obscene times in an FZR and I asked if they used H or Paddle shift. They replied 'mouse - I've been playing this game for years'. I continued; "why haven't you got a wheel after all this time?", and he summed it up by saying "I have a wheel, but mouse is easier for me." - Just...what's the point?
There are more than enough cars and tracks to chew on, it's just that people don't use 'em!
