A little thought for today: When designing the villain for the game, find a villain song for it. Villain song is a great way to express the villain, and to get the hang of him/her. Think about the Dentist Song from Little Shop of Horrors, for example, and see how we get the essence of our main villain in a nutshell, in a moment.
It doesn't have to be a real villain song, though. Imagine a villain that is defined by a song about how the ragged people need help, or about a villain song like Annabel Lee.
A song lie this can bring us the background of the villain, his/her motivations and goals, and even the enemies. We can also get the personality of the villain. A villain inspired by Annabel Lee will be immature and insecure, while a villain inspired by the Dentist Song will be a sadistic person. A good villain song can also give us the way of action most favoured by the villain (like being a dentist in ordered to get paid for causing pain to others), although it's not a must have (as can be seen in villain songs like Pretty Women).
How about you? Do you use songs to create your villains? If so, how?
