I listened to this novella as a two-part podcast from Escape Pod.

The Mars colony consists of the 1000 original colonists and the children who have been born since their arrival, and now the second ship is heading for Mars with another 1000 colonists. The children on board have been playing a game called "Martian Chronicles" for years on Earth and are continuing to play it on the first half of the journey, knowing that their status in the game and everything they have built up so far will be lost when they switch over to playing on the Mars servers and have to start from scratch.

It's a thought-provoking tale of class, business, and colonisation, and no whining is allowed. ( )
