For a beginning video game player, the biggest challenge is t learning the controls and adapting one's motor skills to match them, but rather kwing where you are and where you are going. The landscape of a game is t much different wadays from a real environment. It is also with exactly the same cognitive functions that players move through virtual environments as real environments. These functions could be roughly divided into: cognitive maps and cognitive routes. At first, when the environment is new, the player would try to remember routes to relevants locations, and use landmarks to get there. But as he or she progresses, remembering all the different routes is t efficient anymore. The cognitive map is begin constructed. But video game space is t solid as rock. It is liquid. It could change as you wallk through it. You could warp from one spot to ather. Space could be wrapped, inverted, Escherian, piled up, or fragmented. This causes cognitive strategies to be unreliable, but makes many dazzling 'spatial' effects possible.
