Create Section Views
Section views assist designers in visualizing how the game world will appear upon completion, similarly to layouts, with one fundamental distinction: section views provide vertical perspectives, whereas layouts offer horizontal perspectives. Accordingly, most principles outlined in relation to layouts are also applicable to section views.
Since section views depict side views of the game environment, they should be created only if players will observe the vertical dimension of the game world. This typically applies to both 2D games and 3D games that enable players to navigate across multiple horizontal planes, such as different stories or platforms.
