Looks pretty fun -- nothing too over the top for Wii controls.
One of the interesting features of the Wii version is the weapon aiming system. As in other versions of the game, you run around in third-person and zoom in over Sam Fisher's shoulder to shoot. But unlike in games like Rayman, the on-screen reticule for your gun does not move with every tiny adjustment you make. There's a small dead zone right around the reticule to prevent it from jumping around when you try to hold the Remote still, and the reticule only moves when you move the pointer out of that tiny area. It's something you might not even notice at first, but makes steadying your aim a simple process, with the only downside being you have to occaisionally overshoot to get very specific shots.
