AC has always been my sim of choice. I give it a solid 8. The base pack has just gotten so much better over time with all the excellent mods. There is nothing more rewarding than taking a car...any car, around Mugello for a good lap. It still has a few issues but then again which sim doesn't. I wish they'd fixed the 'auto brake' issue on entering the pit-lane at circuits like the same Mugello and Monza. I would then have been able to give it a higher score.
