Thats hardly a strong reason, from a Doylisr perspective.. I mean, it provides no fear of failure on the part of the players. They can just cut losses and run with no real genuine consequences.
Id rather the players HAVE to steal a Star Destroyers to achieve some grandiose rescue/attack plan upon which the campaign hinges. That puts dramatic weight to the plan and the decisions.
"Lets just steal **** for giggles" is not my idea of good motivation.
Depends on the groups you run with. I have heard of a few groups that are the Conductors of the Crazy Train. And a GM willing to let it happen.
