How about adding Geometry Wars: Galaxies to the list?
It was the first time Geometry Wars was available outside of the 360, it was at a cheap price point, had multiplayer for the first time, multiple levels with an upgradable drone ship, and has a respectable gamerankings score of 81%.
Then it launched one week after Super Mario Galaxy and no one ever knew it existed. The Wii had been starved for games and Sierra shipped it on the coattails of arguably the biggest Wii release up to that point. Ugh.
