If you have COD(call of duty)on the Wii then have you noticed that;
1.That when you aim the Wii gun when you've got a target lock on when you shoot the aim go's up to the top right/left corner(depending on what hand you play with)
2.When you shoot,the aim is not on target it is a crooked depending on what hand you use.
3.When you walk you can walk thourgh the nazi's and tree's and if your luckey thourgh doors and get stuck and you have to start the damn mission again.
nev mind, it fixed itself, anyway, metroid prime 3 was the best fps i played on wii, and if u have a ds, and like metroid type games, i suggest you rent MOON for the ds, its a very good fps type game for the handheld system
oh, and for the person/persons with the wii aiming problem, if you havent tryed this already, clean the sensor bar or remote sensor, it might just be dirty cus that happened to me before
