Para o registro, os Buggers (AKA Formics) não recriaram o "Jogo do Gigante" em Eros (que na época da segunda invasão já estava sob controle da Terra), mas no planeta habitável mais próximo da Terra; Originalmente conhecido como "Ender World", mas recentemente renomeado como Planet Shakespeare
In addition to recreating the shape and feel of the game world (out of concrete) in an attempt to posthumously communicate with Ender, they also left a cocoon with a fertilised female queen for Ender to find and take to a new world after humanity's fear of the Buggers had abated.
A busca de Ender para demonizar a si mesmo (aos olhos de seus companheiros humanos) ocupa a maior parte do interregno de 2000 anos entre 'Ender's Game' e 'Speaker for the Dead'
The hill was hollow. A deep depression in the middle, partially filled
with water, was ringed by concave slopes that cantilevered dangerously
over the water. In one direction the hill gave way to two long ridges
that made a V-shaped valley: in the other direction the rose to a
piece of white rock, grinning like a skull with a tree growing out of
its mouth. "It's like a giant died here," said Abra, "and the Earth
grew up to cover his carcass,” Now Ender knew why it had looked
familiar. The Giant's corpse. He had played here too many times as a
child not to know this place. But it was not possible. The computer in
the Battle School could not possibly have seen this place. He looked
through his binoculars in a direction he knew well, fearing and hoping
that he would see what belonged in that place. Swings and slides.
Monkey bars. Now overgrown, but the shapes still unmistakable.
"Somebody had to have built this," Abra said, "Look, this skull place,
it's not rock, look at it. This is concrete.”

Only me, he realized. They found me through the ansible, followed it
and dwelt in my mind. In the agony of my tortured dreams they came to
know me, even as I spent my days destroying them; they found my fear
of them, and found also that I had no knowledge I was killing them. In
the few weeks they had, they built this place for me, and the Giant's
corpse and the playground and the ledge at the End of the World, so I
would find this place by the evidence of my eyes. I am the only one
they know, and so they can only talk to me, and through me.
