I know the answer.

What's needed to start, for everyone to just know how to incidentally rp, is having the Jedi Exploration Corps and plot out from its Council of Reassignment.

That's the Republic entry for it.

[i]There're even RPG books. "STAR WARS Savage Spirits" is the Jedi Exploration Corps one.[/i]

With Ruby unModded I think, since it's still seen at the frontpage-sector, that Role-Playing here is still indubetibly.
