That's one thing about roleplaying games. You can be in them for the long haul. And you can put them on hiatus for various reasons - people move away, go to university, get married, get a job, have kids, other unimportant stuff that gets in the way - and still come back to them at any point in the future, and the gameplay will be just as good as you remember it. It won't feel outdated.
Oh, what? What do you mean Second Edition, Third Edition, and Fourth Edition? All the real roleplayers are still using First Edition! And loving it!
Now where did I put those weapon versus armour class adjustment tables...?
Adam: Right, door's locked. I guess you're secure. Now what?
C-3PO: Wow, there's enough oil here for a bath. Do you mind? I've got such a bad case of dust contamination, I can barely move!
Adam: So... you're a robot too, right?
C-3PO: A protocol droid. C-3PO, human-cyborg relations. And this is R2-D2.
R2-D2: I don't do oil baths. You're going to have to clean me manually.
[SFX]: < doop beedle boop po-ka-buzz whir ding kibuzz >
Adam: Er, okay, fine. I start cleaning you. Why am I cleaning you?
R2-D2: I've got a lot of carbon scoring. We've obviously seen a lot of action.
[SFX]: < doop buzz ta-boodle doosquee beboppity >
C-3PO: What with the Rebellion and all.
Adam: What Rebellion?
C-3PO: Well, it's a long story.
R2-D2: We've been playing this game for six years.
Adam: Wow. That was three consoles and two PCs ago. And you guys have been playing the same game all that time?
GM: Thank you.
