The thing about robots is that once you start treating them as sapient beings capable of being characters (in the roleplaying game sense) in their own right, they immediately get all sorts of other baggage attached to them that really should only apply to organic beings.

An example of this taken to extremes is Futurama, in which the robots are ridiculously human to the extent that there are unemployed robot bums, disabled robots, criminally insane robots, and an orphan robot with one useless leg and a crutch instead of an arm.

Star Wars doesn't go quite to that extreme, though when you're roleplaying it, it can just be fun to go a bit further than the source material.

R2-D2: <sigh> All right. I guard the ships.
GM: Some combat droids enter the hangar. They're a type you've never seen before.
R2-D2: Screw this. I bolt. 19 for Hide.
{cut to Anakin and Obi-Wan in the lift}
GM: Meanwhile, the lift you're in stops suddenly.
Obi-Wan: Maybe you shouldn't have killed the operator droids.
Anakin: It's just a lift. How hard can it be?
GM: The only interface is a droid data socket.
Obi-Wan: This is supposed to be an advanced technological civilisation and they can't even do lift buttons?
GM: What, and put the lift operators out of a job?
