Nah, its not the games its just the Wii-mote. It doesnt jerk alot, but it does a little. Also since it is pretty precise your moves alot since its practically impossible to keep your hand completely still. But with a mouse/analog, you can keep still easy.
I still like the Wii-mote aiming alot, but its more of a entertaining/easy fun. Im more into competitive/hard fun and I really dont see myself getting competitive having to aim with a Wii-mote the whole time.
