Hi Greg welcome. There's a couple of iRacing threads under the Game Discussion section of the forum (filter for iRacing prefix). But it might not be up to date with all the latest content as most of our members have moved over to AC on PC. I would rexommend you buy tracks over cars. Pick a car you want to race and grab the season tracks from.the schedule. Keep an eye on which series have popular session times that suit you. There is another website that can help with that, I don't remember what it is but there will be a link in the iRacing General Discussion thread somewhere. We don't have a dedicated iRacing league running at the moment, our members who are still iRacing are running the official series.
gt3 is quite popular at the moment mate just look at the series schedules most seasons will run the same couple of tracks
Yep. for probably less than half that cost you could grab Assetto Corsa with access to as much free mod content as you like and come race with us on Monday nights
