Creating Emotion in Games: The Craft and Art of Emotioneering

Here's our case study game scenario:

You're a police captain in an elite unit. You fight back the provoked and angry mob that is trying to kill Jason Falconer, a prisoner you're guarding.

He's been accused of treason, and they want him drawn and quartered. Not that you like Falconer but guarding him is your job.

After the fight, one of your lieutenants tells you he's never seen anyone fight like that, and that he's glad to serve under you. My guess is you'll like that junior officer. We all love admiration, and thus this builds Chemistry.
