One of the only points on which I find myself disagreeing with the article is the implication of a worldwide cultural homogeny when it comes to gender issues; it needs to be noted and acknowledged that Twlight and Other M are products of two different cultures with two different stances on what constitute masculinity and femininity.
That said, if the article-writer means to imply that there is a parallel cultural hegemony the there's nothing to argue with on that point. Other M is definitely the product of Sakamoto's mind, which in itself is the product of a culture where a problematic definition of femininity is more accepted.
THe article doesn't convey something else, though, because it can't: the game isn't even about Samus, or Ridley, or the Metroids; it is almost solely about Adam. One can argue that it's about Samus's relationship with Adam, and I suppose it is, but Samus herself being the narrator places all of the narrative focus on the character of Adam himself, so that even the opening cutscene depicting events in Super Metroid becomes something like background noise against which the drama between Samus and Adam is played out. This is doubly problematic because it means that the way Adam treats Samus isn't just one aspect of the story, it's the point of the story, the moral of the story, the single event around which her character is set to revolve for the rest of Sakamoto-controlled continuity.
Of note:
The lack of feminine perspective in this topic (and this board in general) is something that I think leaves these discussions lacking.
