I haven't either, but PTSD doesn't exactly gel with juvenile male power fantasy, so I'm not exactly surprised.  Then again, I tend to shy away from action/hero/war/fantasy games, and the games I do enjoy tend not to deal with scenarios where PTSD would be a likely element.  A 30 second freakout just doesn't seem like a such a big deal to me though, and certainly not sexist.  A male would fit into the exact same scene, identically as presented even, and no one would ever say that.

Also, Sakamoto didn't work on Metroid 2 or the Primes, just the original, Super, Fusion and Zero Mission.  8-16bit cartridge games don't exactly give all that much room for narrative excess, though he did consult heavily on the mangas, which Nintendo considers canon.  They should probably release them here honestly, they're not bad fanservice.

'By the boys, for the boys' is probably the worst excuse I've ever heard for the permissive sexism this industry is plagued with.  That sort of boys club mentality is precisely the problem.

And as far as the freakout itself, Samus thought she'd killed Ridley and blew up the planet he was on.  In the manga he'd told her as a child he can escape death by consuming the flesh of others, the realization of that being true likely just heightened the shock and may have helped trigger the response.  That's how PTSD works, it's not predictable, and anything could trigger it really.  Plus it's also not like we really saw Samus response one way or the other in Metroid 1 or 3, though she did also inexplicably pause for several seconds when first encountering Ridley in Super Metroid , which allowed him to roid-nap the baby and take it off the space station.  Perhaps that was the 16bit portrayal of shock/hesitation/panic/PTSD? 

So doing a breakdown at this point is not justifiable.

BTW, I saw a video of the scene, and I found my new "Aang Ain't White". Samus Does Not Gasp!

Originally i was quite violently opposed to that Ridley scene, but hearing the debate on both sides i can see the legitimate points on both ends, and i would guess that the scene's offensiveness comes down to execution. Given that Samus is always explaining everything in internal monologue, they could've explained *why* she was terrified (though they did a little with a flashback to her child self), and her suit malfunctioning while in his claws seems a little too convenient by any standard

But while Samus should have confidence that she's killed him 2-5 times before this, she could also be scared because she never seems to be able to kill him dead.

I have deep seated, childhood originated, phobia of sharks.  I've confronted that fear in my adult life, directly even (with a REAL shark), but I'm still liable to freak out if caught off guard by one.  Hell, I could barely get through Endless Ocean 2, that game was traumatic at times for me.

I envy those of you who've never legitimately feared anything before, and seemingly can't reconcile how it's even possible.  Lucky you.

In the manga Samus met Ridley, had a PSTD, was completely useless for a while, Then she got better. There is no point in portraying Samus like she goes like this every time she meets Ridley, otherwise she should have died in Metroid 1.

I know.  But, PSTD isn't something you really 'get over', the trauma causes a permanent damage.  It's something you cope with, or at least try to.  And for someone as emotionally stunted and distant as Samus is supposed to be, with basically no support network to fall back on, that's likely even more difficult.  

Samus was caught off guard, by surprise, and she relapsed.  That's not exactly abnormal, or even unlikely.

Then she should have died in Metroid 1 because there was no one there to help her, would have made a downer ending, but it would have fit Sakamoto's vision.

The game isn't even out yet and clearly going by all the reviews so far, it's a subpar Metroid game.

Worthy of 40%? I don't think it could possibly be that bad or it would have been delayed but most of her criticisms are fair. The whole sexist issue is not though.. She mentions that she can't use her items until 'a man tells her to' in the video but we've been told that she chooses not to as she made the mistake of not following orders previously and wants to prove she's disciplined now.

Super Mario Galaxy was a fantastic reboot of the Mario franchise, Metroid: Other M has seemed to miss the mark.. Hopefully Zelda: Skyward Sword can be more like Mario than Samus..

Edit: Sakamoto saying this is the perfect Metroid experience is telling of what needs to happen to him when it comes time for a new Metroid title (He needs to stay far, far away)

Again, these sort of responses are unpredictable.  And afaik, we don't have much backstory on Metroid 1's setup outside the bounty order on Mother Brain, so Samus likely went in expecting to face Ridley and able to prepare herself.  Which is... well, different than what we have in Other M.

It is shown in the manga, Adam gives her bombs, while a ghost of Chozo shows her were the Varia suite is, and that makes her practically invulnerable to Ridley's attacks, and here is a little exchange were it proves that Samus got over her problems with RIdley.
