Yesterday we started Jewel of Yavin. My group got the job and went directly to the museum to spy out, where everything is and what the security is like. They hid in the storage room of the souvenir shop and at night broke into the storage room for the cleaning droids, and discovered the waste duct.
Now here comes the problem: The auction will be in 2 days (game time). But the force sensitive in my group only wants the gem, not the 250.000+ credits. So she suggested to steal the gem right away, instead of waiting for after the auction. And the group, while still hesitating, could agree to that plan.
For me as a GM it would be a disaster, because they would skip great social encounters, the cloud city grand prix, the hacking of the bank droid, and the real heist (stealing the gem after the auction).
So how could I, instead of talking to them out of play about that they would skip three quarters of the adventure, or railroading them too much, "encourage" them to play the rest of the very cool adventure, instead of leaving now after a quite okay, but not nearly as interesting break in?
