剧本中，空白的这一栏也是必须填上的才能完成吧？
也就是说，只有明星格可以空着，是么？
英文说明书上说的是
A screenplay is considered completed once every mandatory space is filled.
The star space does not have to be filled. If this space is still empty once every other
space is filled, a star tile may no longer be placed on this star space since the screenplay is
now complete.
我的理解是也必须完成，因为下面只补充说明 star 可以空白，也没有地方说 空白格不算 mandatory space。
