You will notice there are four choices each time you respond to people or answer questions asked to you in the episodes.
Has anyone gone threw all of these separate choices and decisions in the entire episodes and obtained very different outcomes. If you take into account every answer and decision and work out the combination of these in total then this means the story can change differently?
If multiple teams of people did this then a lot of secrets,easter eggs,alternate outcomes would be discovered in the form of your and other characters responses and choices threw out the entire episodes right?
Would be worth hunting around and would give those who have finished the episodes something to do while waiting for series 2.
EDIT: Here is where Telltale games constantly remind you choice matters
