Personally, it’s Faith from Farcry 5 for me. Uninteresting dialog that can be summed up to “I was bullied once” and that’s it. Literally every other character is so much more interesting. Jacob gives you a sequence where you run through a gulag which he then uses against you, John tries to kill you and is openly hateful towards you plus is a character you get to interact with, and Joseph is a lunatic who was right.
Since we’re on the topic of Far Cry, pretty much every single character from Far Cry 6. The gameplay was fun but the story and writing was so incredibly bad that I had to force myself to complete story missions.
