It's alright, pretty short, gives a general idea of how the game works. Except that it tells you to get every infernal you see xD
We observed in our labs that new players had some trouble understanding why they should make a purchase, and what traits mapped to which champions. New players tended to miss opportunities when they were presented. So, we decided to double down on trait comprehension as a concept -- the thinking was, if we ask players to collect multiple Inferno champs in multiple shop scenarios, it would drive the concept home. Plus, we wanted to appeal to all the pyros out there.
