What challenge do you fucking hate the most in days gone?
For me, it's any of the racing ones. I like racing games, don't get me wrong, but the devs seemed to miss the memo that racing games are at their best when their car/bike physics are actually well tuned and don't feel like you're trying to drive on a linoleum floor thats had a barrell of shampoo poured on it.
Never mind the physics, but you also want me to run over freakers to get gold, which sometimes feels like trying to swat a fly using your piss
Also, drifting, which slows you down, when you're on a time limit, which can cause you to miss the ramps you need for airtime.
