GM: They've sealed the door to the bridge.
Qui-Gon: I cut through it with my laser sword!
Obi-Wan: It's a field of plasma. It'll slice metal like a hot knife through butter. Otherwise there's no sense to this campaign—
GM: Huh? Oh, sure, yeah, go ahead...
Obi-Wan: Boo-yah! Is there nothing these puppies can't do?
GM: Heh heh...
Qui-Gon: Wait a minute... Why is he laughing?
GM: They close the blast doors, which are ten times thicker.
Qui-Gon: Is that all? I stab my sword deep into the metal!
Obi-Wan: It'll melt a hole right—
GM: Yep, yep, fine...
Obi-Wan: This is too easy.
Qui-Gon: No, we just kick ass!
GM: Oh look, you're surprised by a squad of advanced battle droids! With plasma-proof energy shields!
Obi-Wan: Yeah... I act surprised.
