-Was the first human in space, because she volunteered to test the untested mercury capsule, almost died and spent months in recovery, only to be completely fucked out of the credit of even being in the program(because Gagarin got to space a few hours earlier then she did).
I thought it was classified because of sexism (sending a woman into space? Madness!) and the fact that they'd sent someone into space without radiation shielding, which might have raised a few eyebrows.
And of course, her "The world used to be united" because Russia, China and the US were briefly on the same side during WW2 due to a common enemy, except that really doesn't count at all. It was mainly that 3 future superpowers(the UK got left out of this weirdly, because China future rise was more important to the philosophers then the UK's world spanning empire for a century or so prior to WW2) were very briefly fighting the Axis powers(and the US was late to that particular party).
Well, there's that, but even then, IIRC, part of her desire to see the world united was her seeing the Earth from space - one world, no visible borders, etc.
I mean, taking Metal Gear seriously is the wrong approach to start with. It's a series that has a lot of stupid parts with the occasional brilliant one. It's just some people seem to forget all the stupid ones because of the occasional brilliant bit.
I think it's the other way round. Metal Gear treats itself seriously, even if the plot is convoluted. The "stupid bits" may be memorable, but they're scattered throughout the games and in the background, rather than being the focus.
You be surprised how many people I've met at a game store, that took metal gear100% seriously. Some of them were teenagers, but you had dudes in there 20s and 30s that love the series unironically. One Game Stop employee through a biatch fit, because Rising had a more goofy tone than what it was originally going to be when Platinum games took over. Oh, and he hated Raiden a lot.
Disliking Raiden isn't exactly a fringe position.
But I would have certainly been in the guy's camp, or at least, adjacent to it. I haven't played Rising, so I'm reluctant to comment too much, but based on everything I've seen, Rising is a case of where you took a series that was serious with comedic bits, then ran with the comedy and ratched everything up to eleven. I mean, yes, cyborg ninjas were in the series prior to this, but compare this:
To this:
Bearing in mind that the former is already a scaled-up version of the original cutscene, and that the latter depicts Raiden going up against what is arguably the most powerful Metal Gear model in the series.
Rising is really in a league of its own, for better or worse. I think even Platinum knew it, considering it was called "Metal Gear Rising: Revengeance," rather than "Metal Gear Solid: Rising."
