BKGaming: 100% achievement completion could unlock special wallpapers for the game you completed. [Suggested by Alexim]
Lazarus_03: I do like in-game achievements, but I disagree with this; you shouldn't be forced to be a completionist to get more privilege on something you already own. How about being able to choose from the wallpapers available in the 'goodies' section?
mqstout: Oh god no, why would someone want that??!?!?!!?! Burn in fire. (But yes to the holiday ones.)
Lazarus_03: ^Also this. In this way there would be a small prize for those who take the trouble to complete them, while those who are not interested would still have available the basic background of the game.
More than anything I proposed it because many games have more than one very nice artwork and would add variety of choice. Happy that you like the idea of backgrounds based on past sales.
