You know what I think the problem is? Too many gamers are getting old and set in their ways. Any new control scheme is going to have a learning curve.
First time I played with the NES controller dpad, I thought "wow, this is too sensitive, I like the joystick better"
First time I played a PC FPS with a mouse I thought "wow, this is too sensitive, I like the keyboard better"
First time I played with an analog stick, I thought "wow, this is too sensitive, I like the dpad better"
I'm sure the first time I play with a Wii remote, I am going to think "wow, this is too sensitive, I like the analog stick better"
But I'll learn to play with it if I like the games, and I'll move on.
