For sim, I utilize iRacing to practice and learn tracks before real life amateur endurance races in champcar and lemons as well as track days.
IMO iRacing physics are so good and the tracks are so well modeled that it's a very effective learning tool. It's the first sim since Live For Speed that really feels close enough to real life for me to forget I'm playing a sim.
Plus traffic management and race craft are so crucially important in wheel to wheel racing & I simply don't get any other opportunity to practice those.
Hey I have a real easy solution to that.
I'm perma banned because I had the gall to play modded MCC from the steam workshop on the day it released, before the moderation team knew modding was legal. I can't even log into Halo waypoint to get help from the Halo team.
I now can't play any Microsoft game, own an Xbox, or use game pass and I refuse to make a new account on principle.
