Uncharted 2 is easier than the first, but neither are that difficult.

demons souls hands down and megaman 9 is just cheap

Crysis on Delta difficulty. Now I dream of Asians firing sub-machine guns at me. They are the smartest, deadliest, most adaptable AI I've ever played against. And it was damn fun. Crysis is my third favorite FPS of all time.

Here's hoping Crysis 2 is even better.

Cherub Crown I think it the item you are referring to.

I only had 1.. and I got "death"ed on my first attempt - son of a ...

Next time he didn't use death once, but the fight was still a bitch, however, his second form was a joke, I didn't realize it was going to be that easy, I was prepared for another long fight, so I finished with 5 TP still, should have used renew instead of switching to combat clinic, probably could have 5 starred his ass, oh well, after I level up I'll go back there and do it again :)

On Topic:

Depending on what you mean by "hardest"

Hardest game: Demon's Souls, like others have mentioned

Hardest game to Platinum: White Knight Chronicles or FFXIII (That treasure hunter is gonna be a bitch)

Alundra on the PSone...... I love and hate that game so much....

"ZELDA FANS WILL LOVE IT!"

yeah right....

Ceberus battle in GOW3 on Chaos. hehe

Gradius 3 in Gradius collection for PSP.

Pixeljunk Monsters.

I like playing tower defence games, but my brain has a low ceiling for getting to grips with the strategy. I can't see myself ever finishing it without a strategy guide.

Contra 4. I could also add Megaman ZX and ZXA on hard, but maybe that was because I tried to beat it with the normal mode only :P. But in anyway, Omega on hard from ZX is impossible.

Fire Emblem: Radiant Dawn

Super Monkey Ball Banana Blitz.

World 10-5 is the hardest level that I have ever beaten in the history of my life.
