When creating character rigs for video games we always set the root of the rig and all the kinematic chains to the pelvis of the character. Is their a specific reason that we do that or is it by convention?

As far as I know, this is because the humans centre of mass is near the pelvis. This is just a convention, but almost everyone does it. But it makes sense to choose a point that is at the middle (not a foot for example) and doesn't move too much.
Let's say you choose the foot as root. If you want to do a walk animation, you'll move the foot and everything moves with it. You have to move it back then. You won't have this situation that much, if you choose the pelvis.
