Firstly, there is the Export Rig, and this is not so unique to 3D character animation. This is a highly optimized skeleton that represents only the bones that the actual actor mesh is weighted to. For a humanoid character these bones would be named: Pelvis, Femur_Rt and Femur_Lt., etc. Vertices of the visible textured geometry, that the player sees, are all attached to these bones with various amounts of strength, so the character will appear to bend and flex more naturally. Sometimes these bones will have physics applied to them, like pony tails. This is less a rig and more of: simply the skeleton that the other rigs interact with, but these are the only bones that go into the game, and we call it the "export rig". Antonio builds this skeletal hierarchy to fit the expected proportions of the character, and character modelers build character meshes to match visible body parts to the locations of bones, so that -- for example -- the bendy part between the upper_arm_rt and lower_arm_rt ends up being where a humanoid creature, as designed, would expect an elbow to be.

...And last, but most certainly not least, we rely on Antonio for creating rigs that provide controllers that allow the animators the maximum amount of flexibility when creating animations. These 'control rigs' are specialized for each character/creature type, after they've been stretched. They provide controls for jumping, crouching, twisting, grabbing, etc. They provide inverse kinematic and forward kinematic transformations, physics blending, following, squeezing, etc.-- whatever is required, actually. These controllers and extra bones are for animator manipulation only; they do not get exported. That's why when I said, "he rigs the rigs" I wasn't actually joking. These are rigs of rigs. These are the animator's most essential bread and butter. Using these tools is how they actually create character animation.
