Impossible/Hardest games to S-rank?

I've seen plenty of "easiest" and "proudest" games that have been or can be S-ranked. 
But what about the hardest? 
We all know about games whose servers are shut down and no longer can get multiplayer achievements and such, but I'm more interested in games that have achievements are just to damn hard.  
 
My vote goes to Ninja Gaiden 2

Dragon Age: Origins because of all the DLC that keeps getting released =P. Plus it's impossible for me too through some glitch that won't unlock some trophies. Freakin' annoying how I have the ''Kill 500'' darkspawn trophy but not the ''Kill 250 darkspawn'' trophy -_-'

i imagine that there are some games with multiplayer achievements that no one ever plays anymore.

GRAW has an achievement for being #1 on the world leaderboards

Smash TV, no brainer I think.

Ghost Recon is easily the hardest.

" GRAW has an achievement for being #1 on the world leaderboards "

Trials 2 without a doubt.  I would contend that the Top Score, Top Dog, Inferno, and Superhuman achievements in that all take far more skill and effort than getting to first place in the leaderboard of any shooter in existence, as much of an accomplishment as that may be.

Please be kidding  "

• Race Driver: Grid: The achievement for driving all the cars was glitched on launch, so Codemasters fixed it. Then they released the 8 Ball Car Pack, which broke it again. So they decided not to bother fixing it.
• PGR3: One of the achievements is for winning an Online Tournament or something, which is impossible seeing as Bizarre Creations do not host tournaments with this game anymore.
• Just Cause: The achievement for basejumping 1000 feet is broken, meaning the max possible Gamerscore from this game is 995, from what I know.

i know this isn't what OP really meant, but i think Skate 3 has an achievement that is still impossible to get as of now.

The obvious is Smash TV, isn't it? One, it's fucking impossible, and Two, it's not even available to purchase anymore.

Nope, it's for real. It's called Global Leader or something, and it is worth 40G. Meaning it is an impossible game to get the full 1000 from anymore. Furthermore:

I'm gonna go with that NBA Live or NBA 2k game that you get an achievement for playing online while a set number of other people are playing online as well.

Avatar was pretty punishing. 

Torchlight seems daunting for achievements, for example there are seperate achievements for completing the game on easy, medium, hard, insane... then there's a seperate toggle for hardcore mode (where one death = game over cant reload) and acheivements completing the game on easy hardcore, medium hardcore, hard hardcore, insane hardcore.  And no you can't just do the hardest one to unlock all below. You literally need to complete the game at least eight times and its not short.
 
There are also achievements for modding it however, so perhaps when I look into the mods there's one that drops you at the end of the game so you can unlock those easily, I don't know.  Just looking at them is depressing though.

Shumps. There's always a beat the while game with one credit achievement.

Now, if we can add Ps3/PSN games, then i HAVE to add Trash panic. those achievements are no joke.

I've heard Blue Dragon is ridiculous. Portals achievements, specifically Apature Science is pretty ludicrous.  
My S-Rank in Marathon 2 was probably the hardest, but I didn't really care because I love that game.
 
Usually "hard games" have some stupid ill-thought out multiplayer achievement that no one seems to be able to accomplish.

I'm having a tough time with trials HD just with the Ultimate Endurance one

Bad Company 1 - Get all online awards
some awards are ridiculous and lame, some are straight hard and one or too are just plain hard

I'm sure everyone is aware or the nightmare that is Final Fantasy 11. Each of the achievements is for getting your character to level 80 - or whatever the cap is, and getting some high level skills. Then you have the Expansion achievements for defeating high level bosses and another couple characters to grind. 
Getting the full 1000+ mean thousands of hours of play time and for a game that was abandoned a couple years after it was released.
 
The hardest that I have ever seen has to be Ridge Racer 6 and  Trash Panic, which is bullshit! 
 
Edit: Nevermind, the hardest game to thousand is Kingdom Under Fire: Circle of Doom. One because that game is boring as hell and takes 60 hours to beat with one character. Two, because you have to beat it with all the characters doing quests that are never mentioned in the actual game.  Three because the rest are grind fests. Finally the last few are to beat some of the most annoying bosses ever made. This game was made by people who HATE gamers.

Final Fantasy XI

Guitar Hero III is one hard mother fucker to S rank.

Thing is though, with MMOs you're sorta expected to spend thousands of hours playing them if you're going to see most of what the game offers, I spent something like 5000 hours in Lineage 2 and I never even got close to the max level.

I'm just going to link this and walk away.
 
Edit: You know what? I'm changing it: here take a look at that.

" @Claude: Really? That game should have only taken 6-8 hours. You might be right at the end and since all the points are story related you get all of them just by playing to the end. "

" @Claude: Oh yea...that game is boring as shit. I remember having movies playing while I played it. There are always easier games to get thousands though, why would you choose Kong. "

Because, it's the only game I have for the Xbox 360 that seems easy. "

Definately Star Ocean: Last Hope. Last I heard there was only one person in the entire world with a full 1000 points. Also FFXI is pretty ridiculous.

 Yea, that sounds about right. Careful though...if you're anything like me and most achievement whores, once you get one S-rank you need all of them. "

The correct answer is Final Fantasy 11 on the 360, in which you have to get every character to a very high level.
