It's a very straightforward arcade-style experience, instead of the more in-depth third-person covert-style gameplay that the Ghost Recon series is known for. At the very least, the Wii is getting its own take on the franchise that works pretty well within the restrictions and capabilities of the Wii system and controls.
All of these type of games, as long as they implement the controls well are better than the 30 / ps3 versions. I've had friedsn with 360's come over and are blown away by the controls of the wii version and the zapper. Once you get past the graphics it's the gameplay that counts and have to say the wii controls in a lot of these games makes me come back again and again. MUCH BETTER than sitting there with a gamepad.
