An idea just occurred to me that could potentially give more import to XBOX 360 Achievement Points and their associated profiles: allow the picture assigned to any given achievement to be designated as the gamer picture in one's gamer profile once that achievement is unlocked.  This widening of the selection of profile pictures would lend much towards the individualization of said profiles.  The icon representing one’s gaming avatar would speak to that individual’s skill in or commitment to a particular title rather than their willingness to contribute over and above the price of admission to the publisher’s coffers. 

If Microsoft is committed to innovation in the field of gaming, they will heed this suggestion!
