ABSTRACT
The concept of the third-person adventure game completely changed the way the genre was created, and Sierra had to design a whole new engine to produce Roberta’s idea.
The change wasn't only technical, however. "In the old games," remembers Roberta, "they were stories that you experienced from your own eyes. Like in Time Zone-you're just walking through the trees outside your home, and suddenly there's a time machine. It's never been there before; it's just suddenly there. What is this? You don't even know what it is. This funny-looking machine... You look closer, then climb inside, look at the controls, and before you know it, you're off on an adventure. But it's just you.
