Hardest games you've beaten/attempted

[Caliban113]

Beaten: (After much swearing, and more than a few replaced controllers)

Castlevania I - (NES - 10+ years to get past the Grim Reaper...seriously....there are still tooth impressions in that controller.)
Castlevania III (NES - Unfortunately, the last difficult Castlevania game ever made)
Perfect Dark 'perfect' level (N64 - Probably my favorite game for that system.)
Ghosts and Goblins (NES - when it told me I had to start over cuz it was a, 'fake' Satan, they almost had to call the Sheriff to drag me away.)
Conker's Bad Fur Day (N64) Too bad Rare only works for Microsoft now - they put out some pretty good schtuff
Street Fighter II (coin-op)

Never beat:

Ninja Gaiden (NES- Never beat the last boss)
Castlevania II (NES - Found out years later that there were places where the character had to kneel down for 20+ seconds to reveal new paths. After that, the game practically played itself........Cheap.)
Starcraft 64 (N64 - However, I blame the stoopid controller - only ever got to 'True Colors')
Turok 64 - N64 -Cant remember where I even left off

Toughest RTS level - ever - for me was WC3's 'Under the Burning Sky' (Final Undead mission) on hard - Admittedly, I'm not the best WC player, but I had to restart that one more than a few times.

The first Quake on Nightmare (though that wasn't that difficult),
Descent (I've no idea about difficulty settings in this game, but boy, were the final levels tough)
Wing Commander: Prophecy on the highest difficulty setting (challenging, but a lot of fun at the same time, this is one hell of an underrated game)
Panzer General (old turn based WW II strategy game, I'm not sure I've won a single mission there)

Also attempted beating Myth and Myth II on Legendary (and with No Casualties to boot) many years ago, should dig up the CDs and try it again some day.

God of War
God of War II
StarCraft: BW - Omega

-Diablo1 Hellfire exp - amongst other things, i hated those ranged sucubus Deamons, stop fucking runing away from me and let me kill you, if only they wouldn't walk faster than you and fire while on the move
-Metal gear NES
-Operation Flashpoint (walking for 20 minutes, until something shots you that is a mile away is not fun)
-Kaizo Mario (I wanted to kill myself after playing this, it turns out to be the most soul-crushing game ever conceived, It's so hard I bet they banned it in hell.) This game cannot be beaten by a mere human.

Beaten:

The Ecco the Dolphin series (Genesis ones only, the others don't exist).
Final Fantasy VIII, Ultimecia being the hardest last boss in the series, except for maybe Zeromus in IV.
Final Fantasy IV, see above, which is much harder than VIII.
Super Metroid: Redesign, the single hardest game I have ever beaten, start-to-finish. Haven't gotten all the powerups, though.
Halo 3 Legendary solo. One weekend of Hell, but it was worth it, given no one I know can lay claim to that (the pansies only managed it over Live with two or three people. Ha).

Attempted:
I Wanna Be The Guy, nuff said.
Super Metroid: Redesign, as I was going for a one-hundred percent playthrough before I gave up.
Final Fantasy II, because the leveling system is fucked. It's a shame, too, because Emperor Mateus is so fabtacular with his high-heels, zebra-print clothes, blue eye-liner, and blue lip-stick.

Impressive, I'll add this mentally to my attempted list as I forgot it. Kudos to you, I should do this one again, I ALMOST beat it when my computer crashed... but yes, this thing isn't easy at all...

I think i never finished some of the very last BW Zerg missions.

Black & White: i quitted the game at the raining fireballs level.

Generally, i follow a single logic with games: i play a few levels, if the game keeps flowing all the time, and it's fun, i continue to play it. If the game has too high a difficulty level, and missions must be restarted continuously, giving the sense that you advance at snail rate, i stop playing it.

Black & White is a clear example: the game had a lot of potential, but it had like 5 levels, and very slow = boring after the 3rd level or so.

The bottom line: games should have content, and working difficulty levels, not make the game longer to play, by reloading the same part again and again and again...

-Operation Flashpoint (walking for 20 minutes, until something shots you that is a mile away is not fun)

Oh, yes, i tried the game recently. The difficulty level of the single player portion is ridiculous, it's scripted and scripts fail all the time. It's said to be a realist game, but in the mission when you're alone in a forest infested with enemies, in reality there's just one possible outcome: you die, or you throw your weapon away, raise your hands, and surrender. Ridiculous difficulty.

The multiplayer should be good, i never had the chance to test it.

I convinced one of my friends to do it instead. That was fun.
