There's restraint, then there's restraint; then again, there's also restraint. While it is true that breasts don't move like balloons full of water as in DoA, they are not perky, jaunty rocks that never move ever as in Brawl. Then again, (and I wish Samus' designers would figure this out) a sensible woman like Samus would be wearing something like three sports bras to keep everything held in place, and even as what looks like a C or D cup, whatever there was would be rather diminished.I like Zamus the way she is. Sure, she's beyond fine. She's deep into 'FOINE!' (rhymes with loin) territory. However, with great power comes great responsibility (and a great rack), and Zamus conveys that ideal. She is a fighter at heart, with nothing implicitly sexual about her. She's got the body and the skill, with none of the sleaze.
For instance, look at the Soul Calibur games. Taki in particular. Taki is a warrior of great honor in a jumpsuit, just like Samus. However, Taki looks like a total skank, with pokey nipples and excessive sandbag physics in her animations. Zamus, on the other hand, was an excercise in restraint, and I feel that we all need to respect that. And not make jokes like "I'd like to exercise with her in restraints!"
For once in a fighting game, I'd like to see a sporty, sensible woman portrayed realistically as in the last case. Maybe I'm alone in that.
