You may have heard about the famous 12 principles of animation. Two Disney animators formulated and introduced them in 1981. These principles are really important if you care about how the animation looks in your movie or game.
In Amazin Escape, the game I am working on now, the main protagonist is a jumping lamp. It jumps all the time and certainly different kinds of animations are an essential part of the game. When I worked on them I tried to follow the principles thoroughly.
