the achievement in dead rising where you have to survive 14 hours straight without dying is freakin hard
The achievements in Metal Slug are nigh impossible!
The achievements in Call of Duty 3 and Halo 3, more specifically the multiplayer are some of the easiest to get, they just require longevity, no uber skills like some of the other ones listed.
Star Ocean 4 has single-handedly killed my completion percentage. The achievements are doable, but many of them take an immense amount of time to finish (like the ones for trophies and item creation).
I'm enjoying the game, but I'm not confident about getting more than 500-600 points out of it.
Also, the writer of the article forgot both Chromehounds and Rayman Raving Rabbids as harder-than-expected achievement games.
