The 12 principles of animation number 2#: anticipation

anticipation is all about getting ready for an action for example when someone is about to kick a ball they lift there foot aim then kick the ball making it move. a good example is when you are about to slash somebody with your weapon in fable 3 as the character throws their arm back in to a position where they gain strength as the player we know whats going to happen next. in games the anticipation has to be instant to when the player presses the button or else it can look instantaneous instead of believable.
on the other hand final fantasy XIII while in exploration mode the jumping animation seems like an exaggerated hop instead of realistic jump due to the lack of anticipation. 
anoth example i recently found was a glitch when climbing in assassin creed 3 the anticipation for the character to climb sometimes upwards sometimes misses a action to make it realistic
