Ask gamers what kind of player they are and they describe the player they wish they were, so a designer has to watch what people do rather than believe what they say.

We all, to some degree, lack the self-awareness of how we tick. So we’re all different types of gamers, but if you ask me to describe the type of gamer I am, I might actually be giving more of a picture of the type of gamer I wish I was or the type of gamer I want you to think I am versus the type of gamer I actually am.
