Gameready rigs for blender

Hey Blenderanimators -
i couldn’t really find a rig so far that seems to be ready for games. Do you know any rig for blender that has everything in it to export it to any game engine? Like a driverrig that is used for animating and a single joint hierarchy rig that that get’s baked and finally send to unity or unreal?
I really appreciate any answer on this since i would love to animate in blender and then be able to export it to any game engine. Unfortunately i can’t rig at all so i hope that there’s a rig out there that’s already gameready =)
Thanks,

Poly.
