What online driving sim are you guys playing ? I'm looking at purchasing one but not sure what to get.
Might as well start with one that's free. See if you like RaceRoom. http://game.raceroom.com
There are a few here who are iRacing fans, but it definitely isn't free. It does have the great advantage that you can have a decent race any time of the day or night, assuming you stick to one of the popular classes.
Obviously the best online racing is here on a Tuesday night, which means rFactor 2 might be all you need if once a week is enough.
