Akari,
Were you guys given a clear plot that you had to follow, but just flesh out the story? Or did Lucasarts just give you a very broad idea of what they wanted to see, then left it up to Obsidian to come up with the entire story and characters?
For example, did they say (just hypothetical): we want you guys to make a story and game around a Jedi who was in the Mandalore wars, and we want him to encounter these specific characters (enter list of NPCs). Or did they just say: Here's what you can and can't include in your story. Go to it.
