I believe Asia means a long story sequence sequence to get you in. As in, a story as long as the Odyssey of you just traveling to the main event.
Even i don't know what you just said.
but no, that's not what i meant.
Normally characters have a story they want to get through between when they start the rp, to when the rp finishes. People want their character to have gone through an arc and have grown as a person as a result, during the events of the main story.
if this arc is likely to be long and complex then it wont work considering the time left in the main story.
To give an example, kitt has the arc of the two outcast clan members struggling through their own feelings and the loyalty to the clan and clan tradition. In the end they will most likely end up abandoning the clan for the sake of love, but this will happen slowly over the course of the game.
