The End Game: ENDER the Stars???
From the book:
“So these were the obstacles that the soldiers called stars. They were distributed seemingly at random. Bonzo seemed not to care where they were. Apparently the soldiers already knew how to handle the stars.
But it soon became clear to Ender, as he sat and watched the battle from the corridor, that they did not know how to handle the stars. They did know how to softland on one and use it for cover, the tactics of assaulting the enemy’s position on a star. They showed no sense at all of which stars mattered. They persisted in assaulting stars that could have been bypassed by wall-sliding to a more advanced position.”
