Fable NPC system is so sophisticated the devs are calling it a "life simulator" You build reputation through your actions in the game, then each NPC has a different opinion of you based on your reputation. You might have to become a rich business owner to impress and date one of the NPCs in the game, but another NPC will hate you for being so rich. As a consequence, that NPC could increase the prices on their merchandise when you visit their store. Even small actions such as giving money to the homeless or evicting people out of their houses will impact your reputation, and this can be done at a very large scale, because you could: - Buy every home in the world of Fable - Evict everyone out of their homes - Have every NPC now live on the street Possibilities are quite literally endless here
