What in the end is the difference between "racing for real" and racing online though? I wonder if racing simulators have increased participation in real-life motorsports or if it has actually decreased it? Kids that watch F1 15 years ago used to think "wah that's cool how can I do that" .. and then found out they can get a kart and will do anything to get a kart. Now the same thing happens except they found out they can race on their computer for very little $$. It might increase it because they then get even more interested and end up getting a kart.. or it might have decreased it because they get their racing fix from the online world and don't go out of their way to get a kart.
I don't know what it is about online league races but I really get into the race and also get a bit nervous I guess because I did a 2-hour league race the other day and by the end of it I was sweating as if I had gone for a jog around the club.

If I just do normal hotlapping for ages I hardly sweat at all.
