Let's face it. All PCs want to find treasure. Even if the setting doesn't really support the concept.
We're sure you could find characters in a game of prehistoric cavemen struggling against the forces of nature, bickering about how to split up a bear's jawbone that they just found.
Obi-Wan: —always complaining about me being a doctor, how come you want to be a vet?
Yoda: Because I actually want to be a vet! Not just because Dad say so! I've always wanted to be a vet!
GM: Can you two sort this out at home?
Obi-Wan: Sorry. Um... I keep looking for survivors.
GM: <roll> Oooh. Your search is especially thorough; you're confident there are no survivors. You do however notice something odd in the server room. A hidden panel.
Obi-Wan: I check it out.
GM: Inside is a mass of cables and recording gear, connected to some memory marbles.
Obi-Wan: Hello. What's this?
Yoda: Yay! Pete told me about this. This is treasure, right?
Padmé: Finally! Treasure!
Obi-Wan: We are not looting the Jedi Temple.
