It can be good roleplaying if a PC forms a strong attachment to something in game. Like a loved one, or an adorable street urchin, or a family heirloom with no value beyond the sentimental.

Ah, who are we kidding? There is no love more sincere than the love for a +5 Flaming Vorpal Demonslayer Sword that shoots fireballs on command.

Trooper 1: Hello, we're just looking for a lunatic and his two droids.
C-3PO: No droids here, sorry.
Trooper 1: Okay, thanks. Sorry for the disturbance.
Trooper 1: All right, check that side of the street. No droids here.
{the troopers move off down the street}
C-3PO: I don't see why you're so hung up on that dreadnought.
R2-D2: You don't get it. It's mine. I have the registration and everything. If I give up now, it wins.
C-3PO: You can't control the things you love, Artoo.
R2-D2: But 
C-3PO: It's moved on. Look at all the people living here. The bulkheads are filled with new activity. It's time to let her go.
R2-D2: <sigh> You're right. Mos Eisley is a bustling hive of scum and villainy, a thriving market town. All thanks to the Invisible Hand.
Greedo: Don't worry. There's plenty more fish in the sky.
