Does anyone know how to gain more influence?
To get more on the quests asks me to unlock rules but I lack 1 influence
That usually happens when you give Priti's pictures to Wilson. Don't do that. Spoilers below:
Trick Priti; do NOT force her to strip, that is how you end up with 10. After that, refuse to give Wilson the pics. Offer to get him a hooker instead. Buy him the generic viagra, and enjoy her yourself (that's her, Candy, 7th pic down on the message screen where you post these messages). You still end up with 11 if you trick Priti, but don't get the extra content.
