Concept art is created early in the design process to visualize ideas before finalizing assets. Examples shown include weapon and background concepts later turned into finished digital designs. Multiple stages of refinement are often needed before a concept is complete. Other graphics discussed include pixel art like in Minecraft, textures to add surface variety, backgrounds for menus and levels, and promotional cover art to attract audiences. Collectors editions and pre-orders offer extra merchandise to dedicated fans. A variety of advertising methods are also used to promote games.
