Behavioral Economics & Game Design (in Portuguese)

I ran this lecture for the staff of a Brazilian game studio back in 2021, trying to help lift them in their efforts to make a viable business out of their free-to-play games. It's about knowing principles of behavioral economics and psychologic biases to design around and avoid pitfalls.
The presentation is in Portuguese but it's in fact a translation of my other material in English for my Game Biz course.
