“Video games are often overlooked in the scope of usability testing simply because, in a broad sense, their raison d’etre is so different than that of a typical functional interface: fun, engagement, and immersion, rather than usability and efficiency. Players are supposed to get a feeling of satisfaction and control from the interface itself, and in that sense, interaction is both a means and an end. The novelty and whimsy of the design occasionally comes at the expense of usability, which isn’t always a bad thing—that said, video games still have interfaces in their own right, and designing one that is easy to-use and intuitive is critical for players to enjoy the game.” (Nate Bolt and Tony Tulathimutte – Boxes and Arrows)
