It is not the chest itself, it is the overall design concept and the approach.
You aware her humongous chest only exists because someone accidentally put in a zero in breast size? Aware no one really remembers anything about her?
Look at it this way.
Who is Samus Aran? It is the mystical Chozo warrior in a badass suit who kills Metroids and space pirates, she also is a woman but not everyone is aware of that.
Who is Lara Croft? It is a skank with huge tits that also sometimes fights something. What do archeologists fight? Ruins? Right, she fights ruins.
LOOK AT ME I AM A FEMALE BUT I CAN DO SOMETHING is called female empowerment. It is also bollocks.
Differences:
Holy shit we are boned now.
Boy! You want girl? Pretty girl! Sucky sucky five dolla!
And I do have something against erotic elements in videogames if those do not advance the bloody plot.
You can make an attractive woman without giving her DD and shoving her into chainmail bikini.
Hell, most people don't even like huge breasts. Barring those high on puberty.
I do not want my videogame industry to ponder to teenagers which is exactly what it does.
