Hi all,
If you would like to try a real hardcore Online based sim racing than follow the link below,
www.iracing.com/nurburgring1000
For those of you who don’t know anything about iRacing. Both the tracks and cars are laserscanned. The races are serverbased, so no lagg and equal to everyone. There are very strict rules in races. This is not a racing sim where you try to win the race in the first corner. The races are minimum 25 minutes long with flag system, if you hit another car you get punished, if you cut corners you get punished, a total of “x” amount of faults in a race and you will be disqualified. Every hour there is a race going on, always full house and the races are very close thanks to the iRating system which is similar to Halo’s “True Matchmaking system”. Hundreds of private leagues with support up to 60 cars on the tracks and 4 different classes. Next month Driverswaps system will be coming too, so 6-12-24 hours of Endurance races will be introduced 
If you have any other question about the sim, how it works, what to do not to do vs. vs.
