Wii Sports: First time I used the Wiimote.
Heavenly Sword: As you said, it has great production values, and truly is a beautiful game.
Super Mario Galaxy: Talk about awesome gameplay! I love the physics in this game.
Uncharted: Drake's Fortune: Blew Heavenly Sword away in visuals, and had a great story throughout. This game has shown me what this gen is capable of.
