I've logged just over 50+ hours on this game. I'm now starting to appreciate just how excellent the controls are. A buddy of mine, who owns the PS3 Don's Edition talked about how he doesn't even use most of the controls. The Wii makes controlling the character intuitive. This is definitely a gameplay experience that's been enhanced because of the Wii controller.
The gunplay has a little bit of learning curve, but imagine my surprise during hour # 30, when my hitsquad (of 5 members) took on a whole compound. What was even better was the ability to use the free-roaming control with the Wiimote. You can move around in third person and aim at the same time and toggle back to regular Z-targeting conrols. Freakin' excellent.
Imagine if EA (developer not known) can tighten up these controls...all kinds of gameplay scenarios would open up.
There are a few games out there that really make use of the Wiimote (Zelda, Rayman, Wario Ware)...I will definitely add The Godfather.
Now if THQ can use some of these fighting controls (the grabs and punches, as well as throwing motions)...look out!
