-Player motivation. This isn't the same thing as character motivation (see above). What you want here is to be able to provide the player with enough teasers to keep him going throughout the game, either by revealing critical information, introducing cool, new companions, acquiring new special abilities, and so on. Basically, each stage of the game should ask the question, "Why should the player care?", and each stage of the game should answer it. It is difficult to make the player care about saving some generic fantasy realm if the designers haven't constructed a way to make the player care about its inhabitants, the political situation, or the events that are playing out there?​
