This chapter focuses on the nexus of theoretical approaches to digital rhetoric and new media. It concerns the way online texts are increasingly composed of remixed, multimodal, and collaborative content, changing the relationship between "writers" and "readers", and transforming the way people communicate and construct social worlds. The chapter suggests that Let's Play (LP) is one exemplar of what Burgess terms "vernacular creativity", a mode of digital rhetoric that increasingly describes people everyday media practices. It also focuses on the paratextual media practices surrounding games, and LP content creation and consumption in particular. The chapter discusses the creative content production and consumption of LP as an exemplar of participatory media and produsage in contemporary culture. It describes what is termed the "playful turn" or ludification of culture, and the way in which LP paratexts are a particularly salient and prolific instance of the transformation, and representative of "extrinsic" play practices.
