The videogame industry has found in painting the means to visualize its own worlds. Could the development of AAA videogames imply a revaluation of naturalist painting, turning the concept artist into the new painter of the 21st century? Art has the capacity to represent an image of the world coherent with the ideological approaches from which it develops. Painting has satisfied, throughout its history, man's need to create an image of the world, a representation of the world and imagine new worlds. A practice that would connect with the concept of Open World developed in current video games. We will make a brief review of the representation of worlds in painting through its history, from the idealization in the Middle Ages to the experimental approaches of the artistic avant-garde of the 20th century. Currently, the concept artist would represent the agent of the entertainment industry in charge of developing the visualization of the world in which videogames are developed. The work of embodying these images is done through painting, using traditional or digital techniques. In this way, a review of the classic pictorial keys with the aim of solving current representation problems, rethinking the relationship between art and design or culture and entertainment, would be taking place. To delve into these issues, we propose to study the case of Red Dead Redemption 2 and its relationship with the Hudson River School.
