If your interested. It just detailed how you can make factions like/dislike you and how you can actually make people fans/companions. People react to different situations too. Someone might not like you roasting a chicken in town with your hands, but become a fan if you happen to slay a dragon in town, and then absorb its soul...

I have an interesting fact.
Did you know that the first game to implement consequences for chicken-hate was probably The Legend of Zelda: A Link to the Past for the super nintendo?
After hitting chickens for some time, a swarm of chickens would attack you eventually with lethal effectiveness. I only say probably, because I cannot confirm that LOZ was indeed the first.
