This is something that has been on the back of my mind for a long time but I've only just been bothered now to write it up. Telltale has employed two obvious season structures in its games, and Sam & Max has gone through both.
The first two Sam & Max seasons were structured somewhat like a TV show, each episode had a self-contained plot that is usually resolved by the end of that episode but they all contain little links that hint to and build to the finale. Other Telltale games that have followed this formula are Strong Bad and Wallace & Gromit. The Devil's Playhouse on the other hand is structured more like a movie, with every episode representing an act, or chapter, to one big overarching story. The episodes are still structured but you don't get any true resaloution until the end. Other Telltale games that have followed this formula are Monkey Island and Back to the Future.
One of the bigger differences between the two structures is that self-contained episodes often contain a main area that reoccurs in every episode (with similarly reoccurring characters like Bosco and Sybil), in season's one and two it is Sam & Max's street, and while some might find the use of this area lazy and repetitive others may find it comforting and familiar. In The Devil's Playhouse on the other hand Sam & Max are always on the move and no one location is used in every episode (to my memory).
Which of these structures would you prefer a possible season 4 to incorporate? For those who don't like episodic gaming and would prefer to a more traditional game like Hit the Road I've included an 'Other' option, but only select it if you really didn't like either episodic format. Also, if you have an idea for a different season structure that you'd like to see please share.
