This honestly has brought new life to LFS. I've just raced on a full grid on the access roads around Westhill, and have been cruising and finding racing lines all week with this new track.
I'd often find myself loading LFS, having 2-3 races, and then logging off for the night. I would maybe do this 4 times a week (because I honestly love the game) or more. The last week of testing Westhill I've been going non stop. Likely 2 hours a day or so, and wishing I could drive longer.
Thank you for the hard work devs. I've enjoyed this for many years, and will enjoy for many more to come.
(edit) 2 hours a night is pretty much all my free time with work and whatnot. It would be more like 6-8 hrs if I were unemployed
