Some games (especially smaller ones) have a consistent texture shared by nearly all of its game objects, for example, paper or clay. Having a realistic sound effect that ties closely to the texture is important to maintaining and enhancing player immersion.
Examples:[]
KAMI:
Kami is a paper folding puzzle game where the player needs to fill out colored paper in as few moves as possible. The colored paper has a origami texture and so the sound effects for folding the paper is very realistic. Paired with an oriental themed background music, the sound effects do a good job in enhancing immersion.
Metal Gear Solid:
In Metal Gear Solid, not only that player can hears different sound effect when protagonist step on different places, it also affect the game play it self. when step on steel grid, not only player can hear a bigger step sound, enemies in game are also
more likely to hear protagonist and follow his trail. It sure makes the game more immersive.
