I understand what you are saying, but I think it is a mistake to view or call things as "main challenge" and "bonus/end game". Doing so places artifical weights or importance on each one. Just because something only happens at the end of the match, doesn't mean it is less important than the other challenges in the game. In 2011, many teams did better just doing the "bonus" than just doing the "main challenge".
