Hexic is is the only one that has ever come with the Pro and Elite 360 Pre-Installed.
However, you can always download Aegis Wings or Yaris from XBLA, both are free.
And then you have the Arcade Pack-Ins that are free as well (Uno, Boom Boom Rocket, Luxor 2, Feeding Frenzy and PacMan CE > Hexic as a packin).
Back from the dead, I'm afraid.
