My biggest gripe about these games on the Wii ... is the fact that it isn't a true lightgun game. It's so much different to move a trianulated reticule on the screen ... compared to truly aiming down the barrel of a lightgun.
You know, I thought the same thing. Then I got the Pega Wii Light Gun. I look down the barrell and the aim is dead on. The only place I notice the aim to be off is on the sides of the screen. It aims to far to the left and too far to the right. I think this may get resolved if I get one of those IR Sensor that sits on the top corners of the tv. I think the fact that the IR Sensor is in the middle of the TV is causing this issue.
On a separate note. I find it weird that no release group has released either Ghost Squad or Links Crossbow Shooting.
