A big question in any work of art in any medium is how to convey information to the audience. I don’t mean any information. I mean the type of information that if done badly gets called an info dump, the exposition necessary to get everyone on the same page, so we can get on with the action and drama of present events in the story. This information is important for the audience to know. Otherwise, they won’t understand the stakes or motivations of the characters. Yet, these scenes contain an inherent paradox that has to be worked out or worked around. The audience has to know this information to understand the plot and to understand the character’s motivations, yet this information is only interesting to people who are already invested in the tale being told.
There’s a long history of creators working out novel solutions to providing this basic need in fiction. However, fiction that seeks to create a world and use it as a platform for numerous stories has a bit of an additional issue. There is a tendency to overstuff works created within the context of an already existing world with information because any part of it could be useful or necessary later down the line. Video games have largely inherited this problem. The need to create worlds that the player can inhabit rather than a fiction that exists within defined boundaries exacerbates this problem. Lore can permeate a world with interesting, but largely useless information. The solution to this overstuffing of information in video games has frequently been to make learning about it largely optional.
