Yes, Godfather is said to be a great game.
Hmmm, well Mortal Kombat Armageddon makes use of the Wiimote and is gory. There aren't too many good Wii Games that are gory and make use of the Wiimote at the same time. Scarface should be similar to Godfather. RE4 will be nice, too, but I don't know to what extense it uses the Wiimote aside form aiming. Even though the motion sensing additions in Zelda TP are not too much, it's still much fun to swing the Wiimote like Link's sword and slash through the enemys.
