Ahhh this is where you're going down. The sixaxis's tilt sensor isn't meant for every game, some games utilize it. That adds a small tilt (Pun intended) to the gameplay. With the Wii, every game must rely heavily on the wiimote, and I'd lay wager that you (yes, you) will tire of it in 2 years. You see, Nintendo relys heavy on the Wiimote's functionality. Strongly suggesting that every game will use the Wiimote's sensors. What if gamers want to take a casual game? What if they are tired of waving their arms around? (They WILL get tired) COD3 for the PS3 had players using the sixaxis to shake enemies off of them when they engage in melee combat.. that is a nice touch to gameplay, but does it heavily rely on that? No. So the sixaxis is a nice touch to gameplay... the wiimote is whoring it.
