well it’s an interesting relationship between the physical, the mental, and the emotional aspects of games. Usually emotion in games is brought in to kind of heighten what’s already there. It is rare that the emotions that are involved in a game have a lot to do with winning and losing the game. At least they don’t - it’s not like the emotions will necessarily help you. In fact a lot of times they can get in your way in some games. You get too frustrated, you're too upset you can’t think straight for example. But emotions are like a kind of seasoning in the game. They can make you care more, whether maybe it’s emotions about a particular storyline or a character you particularly care about or you want to help and protect or a character you're mad at and you want to get revenge on them for something they did. Or, other times it involves emotions with other, other players. Most of the time when people talk about their most memorable game experiences they’re the most emotional game experiences they’ve had. So, I think emotional experience are something that game designers strive toward. And it’s part of what makes game design very exciting, you get to play in that space.
