Roger Ebert, in his arguments that games are not art, made a point about art forcing the viewer/reader to hand over control to the creator, and being transported. But this passage from interactive fiction writer Nick Montfort about a seminal text game suggests a framing for understanding interactivity and its place in art that I think is more promising:
Although at first Bad Machine seems to resist reading, it teaches the persistent interactor to read in a new way — not to glance at a surface and appreciate the play of symbols, not to see a confusion of code that communicates only through its visual aesthetic, but to read and understand the novel description of the IF world, and then to move on to understanding its systematic nature. To gradually accomplish this, it’s necessary to investigate the world, manipulating it.
Manipulation as a mode of reading. Forget (for a moment) the relationship between the audience and the absent creator, and the formal attributes of interactive vs. other kinds of art — What does a reader do with that? What does it mean to “read deeply” in that context, when one often cannot explore every path or aspect of the world being presented?
(Hey, I think I just rediscovered reader-response criticism. Maybe I should label a gameshow wheel with different critical approaches and spin it and see what insights fall out.)
