These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Ass Pull: Fortune turns out to be able to deflect projectiles on her own after all, despite Ocelot having just established that she had only gained it from a technological device he just turned off.
Broken Base: MGS1 catapulted Hideo Kojima to becoming the James Cameron of gaming. After MGS2, people began to wonder if he wasn't the M. Night Shyamalan of gaming. Nearly every aspect of the storyline was a magnet for controversy: the Gainax Ending and subsequent attempts (see Metal Gear Solid 4: Guns of the Patriots) to make sense of everything that happened; the pseudo-incestuous relationships of Otacon and Vamp; major plot devlopments occuring off-screen between Snake and Olga, with Raiden restricted to being a non-participant; and, of course, some particularly long-winded sermons from Solid Snake on the nature of free will, identity, the importance of legacy, hope, saying your prayers and taking vitamins. Fans of MGS2 instead find the climax and message of reaching your own answers extremely complex for a video game, and believe it was ruined by the expositions of Guns of the Patriots.
Quinton Flynn's over-earnest VA work, at least for some people. He's certainly a stark change from David Hayter's grumbly delivery.
Even Better Sequel: While the story is a subject of hot debate among fans to this day, almost everyone will agree that the gameplay is a major improvement to the first Metal Gear Solid.
Ensemble Dark Horse: The Colonel (actually a shoddy AI replica) is one of the more fondly remembered characters of the game, to the point of being referenced in future games, and even eclipsing the popularity of the real Roy Campbell. He's such a whacko, a scoundrel, and a creep that you can't help but love him.
Colonel: One shouldn't stoop to vulgar levels just because they've set foot on the battlefield. (under his breath)But I sympathize with you there... Rosemary: You WHAT?
Fridge Brilliance: Since so much of the game is the product of stressed developers tossing gimmicks at a wall to see what sticks, the result is a warped kind of genius: the Big Shell is a crude copy of the Shadow Moses Incident, and Raiden is an inferior agent to Solid Snake. It makes sense to have him muddle through missions with roller-blading fat men, spritzing inanimate objects with water, clearing hallways of lice, holding hands with little girls, cartwheeling around naked, and other indignities.
The Colonel's rather pervy behavior in some of the easter egg conversations. (Seriously, he hits on Rosemary with Jack standing right there!) The real Campbell ends up marrying Rosemary in MGS4, though he's merely her beard.
Substance has Raiden wearing Gray Fox's Cyborg Ninja outfit for VR missions. It seems fun now, right? Well, it won't be fun or amusing after playing Metal Gear Solid 4: Guns Of The Patriots where Raiden does become an actual Cyborg Ninja under painful and extremely tragic circumstances.
Game Breaker: The stinger missiles Snake gives Raiden make the boss fight against Vamp a piece of cake.
The M9 tranquilizer handgun, or the silenced SOCOM. Take your pick. Both are capable of instantly incapacitating headshots from distances that only a Sniper Rifle would remain accurate at in Real Life, the ammo is extremely common, and abusing them almost guarantees you never being seen. The M9 is arguably the better of the two since you don't aim it down the iron sights, meaning the gun takes up less of the screen in first-person view, and the laser is much easier to line up shots with than the SOCOM. Plus, your endgame status is better if you don't kill anyone. Extra points since it's a Disc One Nuke. The silencer for the SOCOM comes literally about an hour into the game later though.
Long-range sniping using a scope and a pistol is possible in this game, as well as in Snake Eater, via a complex sequence of button presses. Go to first-person mode, zoom in, switch weapons while still holding the first-person button, hold the fire button to aim and then immediately let go of the first-person button. Wherever you were looking at in first-person, your weapon will be aimed directly at it, no matter how far you zoomed in.
Harsher in Hindsight: Hideo Kojima called 9/11. He freaking called it. In fact, looking at this list, we should just use Kojima to predict the future at this point.
Lampshaded in sequels. The "New York Incident" is referenced in MGS4, as it seems the destruction of Lower Manhattan took the place of the (comparatively smaller) destruction of the Twin Towers. It also leads to a dramatic rise in private military contracting and increased turmoil in the middle east. It should be noted that in Kojima's version◊, the WTC is about the only New York landmark that doesn't get trashed, which would be funny if it...y'know, weren't.
Solidus' political extremism and secessionist views aren't too unlike the current political climate in the U.S.
Even better: they think they're continuing on in the spirit of the Founding Fathers while having nothing in common with them, and have named themselves after the Boston Tea Party, in the game's case, the perpetrators. In 2009. Kojima: calling the Tea Party a decade in advance.
Near the beginning of Raiden's section, the Colonel talks about how oil leaking out of the Big Shell would be the worst ecological disaster in history, killing all the marine life and ruining the coastline for generations. After the BP Oil Spill in the Gulf, a bit of oil leaking out of the Big Shell (as opposed to rushing up from the sea floor) doesn't seem quite so bad in retrospect.
Snake's stern warnings about the dangers of "turning war into a video game" can seem even more chilling today that they did in 2002, now that military-themed first person shooters (often praised/criticized for their unprecedented realism) dominate the video game industry, and facing off against real people in virtual death matches has grown into a common hobby.
Alternatively, an I Knew It on the part of the game.
The issue of censorship and intel concerning the Patriots, then the PATRIOT Act of 2001, effective 2002. Possibly an I Knew It on the part of the game as well.
A secret security hole being used by the government to spy on and control the citizens? Heartbleed being used by the NSA anyone?
The game was written in 1999. Featuring an extremely militaristic older president named George. It even throws Truthers a bone, seeing as he actually DID attack Manhattan.
In a less horrible, but more meta (how fitting) way, almost everything that got this game hated back when it came out is now a standard thing. Deconstructing video game tropes and linearity has gotten pretty popular, using games as a storytelling platform is becoming the standard, soapboxing along with mindfucks is extremely popular amongst the more artsy and indie games, which gets them love for it, and sodomizing the fourth wall is no longer taboo, but almost expected. Deadpool, for example. Even changing your protagonists has become a far more popular thing, although usually being more upfront with it.
Hilarious in Hindsight: The premise of the game being a computer program with implied sentience manipulating all of humanity and causing a lot of atrocious deaths via a terrorist group all for an "experiment," and that program being voiced by Paul Eiding, gets very interesting when Dirge of Cerberus does something VERY similar for its plot.
Also, Raiden recalling that he never actually met the Colonel even once will sound pretty funny after Metal Gear Solid 3: Snake Eater, where Raiden's expy in that game, Major Ivan Raidenovitch Raikov, definitely knows a colonel.
The cardboard box is labelled "The Orange". Get it?
Inferred Holocaust: Thanks to various cuts within the final version due to the unfortunate timing of its release, Arsenal Gear crashing into Manhattan as well as the results was glossed over.
It Was His Sled: By the time of the release of the PC port of the game (around 2003, two years after the game first came out for the PS2), reviews of the game had already abandoned trying to keep the game's Decoy Protagonist a secret. That, and everyone knows that the game's ending is, err... rather demanding of the player.
Nightmare Fuel: Everything that happens after Emma's death is so fucked up that you cannot tell what is real and what is not anymore. The Fission Mailed screen is particularly disturbing - with the obviously twisted English words and you still fighting alright.
Especially consider the meaning behind the words Fission Mailed, along with "Emit" and "Continent" - all those words carry an ominous meaning toward the villains' next move...
The AI!Colonel's last words to you before you fight Solidus are a hideously rasped and digitally distorted "Our beloved monsters — enjoy yourselves." All the while, it flickers between its recreation of Campbell's face, and a skull, which leers at you.
Older Than They Think: BioShock was acclaimed for its deconstruction of the concept of linearity in video games, but this game beat it to the punch by six years. You could also make a compelling argument that MGS2 predated The Stanley Parable by ten years, particularly the torture room gag with Ocelot.
Sons of Liberty was not the first game in the series to order the player to shut off their console. That credit goes to the first game in the series.
Porting Disaster: The PC version. You know you've screwed up when you fail at porting a game that worked perfectly fine on the Xbox to PC, when the architecture is nearly identical between platforms. It was so bad, in fact, that no MGS game since then was ported from its original console until the HD Collection in 2011 (a full seven years after MGS3's initial release), and it took another two years for any to come to PC (Metal Gear Rising: Revengeance in January 2014, nearly eleven years after the MGS2 PC port).
Protection from Editors: Likely the reason for why the game turned out the way it did. Apparently, Kojima's original script was over 800 pages long.
Seinfeld Is Unfunny: When MGS2 debuted, it was the first "Triple-A" game that Konami had yet produced. It sold millions of copies and received unanimously high scores, despite some rumblings about false advertising and plot twists ripped out of Jerry Springer. Within a few short years, the tide had turned and critics who had lapped praise on MGS2 suddenly hated it. It became (and remains) the poster child for style-over-substance storytelling and creator overindulgence. It seems evident now that the fans who had initially praised MGS2 did so for the wrong reasons. The idea of a successful developer parodying his own smash hit wasn't in the vocabulary yet. And since Kojima has never come out and explained what he was trying to accomplish (at heart, he is a salaryman who takes orders from above), many still wonder what 'went wrong' in what should have been a slam-dunk sequel.
Stop Helping Me!: In the Plant mission, your support team can get on your nerves.
Take That, Scrappy!: "External Gazer" takes a good bit of piss out of MGS2's story, even more than Snake Eater did. The much-loathed romance angle between Raiden and Rose is lampshaded by their VR avatars, the misdeeds of which earned "the combined hate of the entire universe" and whose mere presence "has the ability to destroy a world."
That One Level: Arsenal Gear-Jejunum, where you have to sneak past Tengu guards butt-naked (which prevents you from using your chokehold), and if you get spotted, you're pretty much screwed and have to run all the way back to the torture room to get them off your tail.
Tough Act to Follow: The paradox of MGS2: It goes down a lot better if you play it before MGS1, and yet the double-bluffs and fourth wall-breakages hinge on having played MGS1 first.
The Untwist: Iroquois Pliskin is actually Solid Snake. Word has it they made it as blatantly obvious as possible just to see if anyone would fall for it anyway.
Values Dissonance: Part of the reason for Raiden's lukewarm reception in the West. In Japan, there isn't nearly as much stigma against men with feminine features, and it's actually very traditional to cast them in heroic roles.
Values Resonance: One of the villains' main goals is to try to censor the Internet, only making information that fits the party line available to the public. What was essentially an eight-hour commentary on the Japanese textbook controversy has taken on a newlight a decade later. Bear in mind that the game was released in 2001, long before Internet users were considering this a major concern and absolutely online anonymity and freedom were essentially givens.
Vindicated by History: Though its gameplay was generally praised, the storyline was deemed convoluted at best and exploitative at a few points. However, as years go by, many are finding it to be an excellent early example of post-modernism in the video game medium, as well as a decent deconstruction of But Thou Must games... two traits that would later be championed by the critically acclaimed BioShock.
Waggle: The pressure-sensitive controls are highly awkward (at first), especially for the assault rifles (even after you're used to them). Lightly pushing the button to shoot will make you aim your weapon, while depressing it fully fires it. This is an important distinction, as accidentally shooting guards you're holding up can be very annoying. In addition, movement with the D-pad is also pressure sensitive—pressing a direction lightly causes the player character to sneak fairly quickly, while a full depression causes you to run noisily. MGS3 fixed this, where normal movement is now solely on the left stick and the D-Pad is for sneaking more sneakily.
