Don't waste your time, after the first two games in the series, this one is complete rubbish.
I tried to give it a chance, but it's all in vain. It's getting worse as soon as you move higher than derby league.
Physics and handling are the worst I've ever seen in racing games. Maybe in derby it's just not that obvious.
Cars can jump several meters in the air just because of the smallest obstacle on the road, sometimes even invisible. Brakes don't exist. Damage physics is not even close to what it was in the previous games.

after playing the first three flatout games (the third being ultimate carnage, which was just a better version of the second game) i can safely say that those are a much better experience than this, and they actually have proper workshop support now unlike flatout 4, which was supposed to get workshop a month after launch. its been 7 years since flatout 4 released, and theres still no proper workshop support. the game is definitely fun for what it is, but i just wouldnt play it much over the original games outside of maybe achievement collecting
