But what if I wanted to make a notgame? Do notgames even have genres? I was thinking of just having them walk around and talk to each other (One of my favorite past times is just to observe the patrol routes of NPCs in RPGs). But then what?
that's it! Weave bits of a story into the conversations ... you talk to people, you get little snippets. Maybe the people have different viewpoints regarding what happened in the story. And if the story is incomplete? Let the imagination of the player and the atmosphere of the world fill in the blanks. Them maybe create some kind of 'endgame' ... ie: if you interact with enough people you'll learn to go to a certain location where something happens that provides a conclusion of sorts to the story.
