'Defile her memory' is a pretty melodramatic way of putting it, Meier. It's not like we're talking about a real human being who's passed away here--this is a
game character. One beloved to many fans, sure, but a character in a work of fiction nonetheless. Also, the upper slope of a woman's breast is
not 'cleavage', and Aeris is still modestly endowed, at least from what I can make out in that sliver of a pic. The more realistic CG in Advent Children accounts for the difference, I think--rendering her as flat-chested as you describe in the new style would make her look like either a prepubescent girl or a very pretty boy, and we know she was neither. (The change in style also accounts for Tifa's massive boob deflation between the FF VII CG's and Advent Children. Either that, or she got a reduction sometime over the last couple of years.
) If I can live with a flatter Tifa, then
you can deal with an Aeris who has visible breasts.
