Dimension/Depth/Space/Scale

This is a image of a basement in one of the fighter's guild in the video game Oblivion.  This demonstrates dimension, depth, space, scale, and size in the world of game design.  The perspective of the player is realistic in a way where it is how we perceive things in the real world.  The weapons in front of the player are relative in size.  The sword on the table, for example, looks larger than the two swords on the rack in the background.  In the game, it is actually a smaller sword but looking at objects in a distant it looks as if it has shrunk in size.  All of the objects in the room are relative and familiar in size.  The room shows linear perspective. The farther the edge of the room is, the more narrow it seems from the player's view.
