S2 is not a good value in today's market.
Compare with RFactor 2, Project CARS and others. Don't get mad, but look at Gran Turismo. That game is less than half the price of S2, and has like 25x more content.
For comparison with more physics oriented sims, look at X-Plane. It's around twice as expensive as S2, but has twice the vehicles, and the entire planet to fly around.
As for boredom, the LFS scene isn't very happening. If you're slow, and/or don't want to do leagues for whatever reason, LFS is essentially a single-player game.
There are about 40 people out of 50 thousand playing LFS on my continent. It is not the middle of the night on a weekday. It's Sunday evening.
