Now there's an idea for a game scenario. Let the PCs discover dozens, or hundreds, of identical copies of themselves, and see what they do with them.
On second thought... We never said it was a good idea.
Boba Fett: Why do you need clones anyway? Aren't droids just as good?
Jango Fett: Never trust a droid, Boba. They let you down when you need them the most.
R2-D2: Typical NPC propaganda.
Jango Fett: That time on Naboo, someone cracked the Federation computers and issued a shutdown order for the entire droid army.
R2-D2: Oh yeah, that was me again, baby.
Jango Fett: Of course accessing that was completely impossible—
R2-D2: Not to my leet uber-hacking skills.
Jango Fett: —until I disabled the authentication routines in order to deactivate the ship's security systems.
R2-D2: I totally would have hacked it anyway.
Jango Fett: You see, a droid army is vulnerable to a single point of failure. So I cloned the only person I trusted—myself—to make an army.
Obi-Wan: If I cloned myself, we'd be able to pursue multiple leads effectively.
R2-D2: If I cloned myself, we'd fight to the death and the winner would be the new me.
