Lo-Fi Games

It would make sense that if some shop owner finds one morning that someone stole his goods, and near the same time a group of foreigners arrived / left, they were marked as "suspects of thievery" for some time and the twon guards check their backpacks looking for stolen items of their town. Then they could be offered to peacefully being imprisoned for X time or fight.

This is a very good idea.

Good idea, thievery is way to easy to get overpowered with as soon as you are good at it.
