If the field of view is increased, it will also increase what can be seen in the game
world.
Figure 8.5
illustrates a sample scene—first viewed with a 65° field of view
and then viewed with a 90° field of view. Notice how in the wider field of view,
more of the scene is visible. Some might argue that players who use a wider field
of view will have an advantage over those using a narrower one, especially in a
multiplayer game. But as long as the field of view is limited to say, 120°, I'd argue
that the advantage really is fairly minimal.

If the field of view becomes too large, it may create the
fisheye effect
, where the
edges of the screen become distorted. This is similar to what happens when an
ultra-wide angle lens is used in photography. Most games do not allow the player
to select a field of view high enough to actually distort this much, but certain game
mods do implement this behavior.
