Terrible AI/bounty system.

I leave San Denis and get ambushed by 5 of Bronte's men, they open fire first and I defend myself and kill them and every npc in the area completely ignores them and reports me for murder and cops flood in a shoot me dead. You get punished for defending yourself in this game, even when you didn't instigate.

Even when challenged in a duel in Valentine, the law engages me afterwards and shoots me a couple times before the terrible AI corrects itself and they leave me alone because the game finally realizes that it was a duel and corrects itself.

Terrible, just terrible.
