First off Just want to say I love the game.
I was thinking of a way to increase some choice in the adventures by having a card that is a location card within the locations you are investigating.
For instance in your pile for town square you could have another card that opens another location to adventure in. The location could have some interesting item or what not to make it interesting. However, you don't get added time to your blessing total timer. This makes it interesting to investigate but not without sacrifices.
This also could be used instead of a villain the players have a choice card that they have to vote on to see which route they take in the adventure, this could also lead to different rewards.
Feel free to expand on the idea, it is just a quick thought.
