To become a video game animator you shouldn't try to start your own game development team, but rather look to join one. To be a good video game animator you must have skills in modern computers and art. It is a good idea to get as much practice as possible. For 3D animation it is best to learn the basics of modeling versus trying to learn how to use different programs. Animation is not only done on computers, but also motion capture. As technology advances, motion capture is becoming more heavily used in gaming development. There are many different universities and schools that can provide an animation education.
