The best part about Knee Deep, Act 3 is the fact that all those decisions made throughout the game seem to finally have an effect. There's something strangely exciting about seeing notification that something terrible or awesome happened because of your specific choices.
That being said, I personally don't know that alternative routes exist, but the election results I received mostly felt appropriate with the overall story. It would be nice if there were an easier means of adjusting past decisions in order to review differences between segments, however. Additionally, it is still very confusing to have to select "New Game" in order to continue with your current stop on the next Act.
