no, I wouldn't want to spend $200 for a single game.
However, I would love a tank game that used the Wii controls. Hold both controllers vertically and use them as joysticks, 1 for each tread on a tank. They did this kind of control in a Monkey Ball minigame and it worked well enough for a mini game. So, you'd have complete control over movement, joystick for looking around, C,Z,A,B, and d-pad for weapons and actions.
