Let’s talk a little bit about the term “fourth-person,” which is something we’ve used over the past year to describe the way you interact with the main character. Basically, the character is not your avatar and you are not in control of him. Instead, you have to find different ways — mostly through environmental interaction — to guide, influence or even force him to explore and fulfil the purpose of the world. This indirect control is what we refer to when we say fourth-person.
