The aliens wanted a robust game show with highly motivated participants fighting to the death to win their races and their daily survival of the fittest challenge.
It wouldn't be much of a game if there were thousands of suicides every day, and leaving only a small handful of participants.
They had long learnt that if left alone and completely to their own devices, many participants would fall deep into depression, and many would choose to commit suicide rather than continue to fight on. Even the best players were not immune from this.
For a time, their viewership plunged, and their gambling ecosystem became flaccid.
However, one day a Void Walker claimed that the participants must be given a ray of hope and some sort of a society, a public forum which they could access and feel like they were part of a greater community of human beings, for them to have the greatest motivation to live, to fight and to succeed.
