That's all really, just excited to have another dirt racing option. Also lots of other updates. It's pretty nice that if you had the 2020-2022 season pass you have access to the new content already.
A Pt2 of the Adrenaline Pack is already in production and will take AMS2 to even higher extremes - owners of the AMS2 2020-2022 Season Pass and of the AMS2 Premium Expansion Packs are secured both parts at no additional charge.
I totally agree, the ACC update made the game feel much better to me as well.
AMS2 has always been a tier below for me because I found the behavior at the threshold of grip to be very weird and almost slightly unpredictable.
The F1 car I tried with the update seemed so much better and I hope it transfers to the rest of vehicles the same way.
