I remember playing Spec Ops: The Line, amazing game that seperates itself from many modern millitary shooters, I think I had beaten the game 4 times on my PS3 2 years ago. Anyways. I do have to admit that the controls in Spec Ops are awkward and unresponsive of also which the AI, despite being aggressive and at your service to kill you, they can be stiff at times. The game can be challenging, though it can be cheap as well.

As for WAW, I am in the mood for a lovely walk today, suddenly, 400,000 grenades are beneath my feet, and now, I'm ded, 'nuff said.

COD 4 on Veteran really annoyed me. 

With a touchpad and keyboard, it was a pain in the ass. I play it on a laptop since it's the only way I can play it right now. Well, it's frustrating trying to move the camera by sliding the finger on the touchpad, and even worse shooting. I still prefer playing it on my PS2; I'm not a Keyboard+Mouse person. Although, I did much better in Max Payne 2 with the touchpad.

Pooh's Home Run Derby

i dont think anything has ever frustrated me to the extent this thing has..

I threw my DS in frustration at Pokemon Pearl. I was tired of running into Pokemon in the grass. Also, every Zelda game I've ever played eventually gets to a point where I'm totally confused/frustrated, so I put it down and never pick it up again.

cod:waw veteran difficulty. it was a looong time ago, but i remember being stuck on single checkpoints for HOURS and places where it would literally take 5 minutes to inch 3 feet forward in prone (i did end up completing it)

catherine babel levels, fk that shit

The Legend of Dragoon. It is so slow and boring. The Playstation has to stop and think for 2 or 3 seconds every single time you press a button. It drove me nuts. Time has tied that game up and raped it til it died.

Easily Super Meat Boy! That damn game even has levels inspired by I wanna be the Guy for fuck's sake!

Just about every tail/eavesdrop mission in Assassin's Creed 4. Wanted to kill someone.
