Here are a few games that I am currently working to get all of the achievements,

Bioshock

Halo 3

The Elder Scrolls IV: Oblivion

Some of the Achievements in Bioshock are a pain in the a**.

First I got the red rings of death, and I got that fixed, then I got a message that said "This is an Xbox 360 Game Disc, please insert into a Xbox 360 Console." and I found out that the problem was, I needed a new Disc Drive. and I got that Fixed. Its times like these that make me pissed at the Microsoft, They released the 360 way too early, and I think they are going to do the same with the Xbox 720. The Xbox 360 is my all time favorite game system, but the only company that was smart in the releasing of their game system was Nintendo. I'm not that much a fan of the Wii, but for the lack of a better term, The Wii is perfect. As far as I know, there is no problems to speak of with that game system.
