In essence, the aliens treat all of Earth like the titular character in The Truman Show in order to maintain the show's integrity. In the 2008 video game Spore, which simulates the evolution and life of species on a fictional galaxy, intelligent species in the "Space Stage" cannot contact those in previous stages, which did not unify their planets, nor develop spaceflight yet. However, they are allowed to abduct their citizens/members, to create crop circles in their terrain and to place in their planets a tool called "monolith", which accelerates their technological evolution.
