Umbrella Chronicles is a retelling of all the RE games involving the Umbrella Corp. plotline in light-gun form, using the Wiimote as your gun. I doubt it will be worth a purchase, but perhaps a rental. Soul Calibur Legends is a hack-n-slash set in the universe of the Soul Calibur fighting games using gestures to control your sword attacks. This one looks pretty but if they don't nail the controls it will end up a mess, so don't raise your hopes too high for that one.
Alternatively, I've heard that the Godfather: Black Hand Edition is pretty good.
