Roll credits, bring up the music, and fade out. Unlike the writer of a TV series, however, the gamemaster doesn't know exactly what the main characters will say or do. He must prepare each encounter situation, present it to the players, and let them react to it as they wish. For that reason, the gamemaster must have some flexibility in how the plot of the adventure proceeds. If the player characters react in an unexpected manner, or fail to accomplish some critical step in the adventure, the gamemaster must be prepared to make it up as he goes.
Some characters prosper and gain wealth, fame and rewards.
Some just run into more and more trouble. Some may die or leave only to be replaced with new characters. It is like one episode of a TV series. It has a definite beginning, a plot or story to be followed or created by the characters as they go, and a definite end. When there is fighting or other direct conflict to be done, things get a little more formal so there is no confusion.
