"Jane! Get me off this crazy thing!" ~ George Jetson
Except this loco-motive will be the end of him.
Nicely exciting setting, plus a super simple and immediately playable story and backstory, plus easy to handle mechanics. An assumption appears to be needed for what a round consists of: likely each player taking their turns in an agreed on order.
This game will have to be a lead in to another that actually deals with a dead sun, though.
