That's pretty cool. I got my grandmother of 80 to play some Wii Sports and Rockband, but that was the extent of it. You could get her one of the crossword or Sudoko games, if she's into that kinda stuff.
My Games of 2011:
The Legend of Zelda: Skyward Sword
Elder Scrolls V: Skyrim
Super Mario 3D Land
Uncharted 3: Drake's Deception
