I have played Half Life and Counter Strike since 2001 and many others since, so I have some years of experience in playing First Person Shooter games on computers, with mouse and keyboard. While I am not very good, I manage to almost always be in top 5 players on my team.
However, when I play on the PS3, FPS games like Wolfenstein, or games that are not FPS but occasionally need some aiming like Uncharted or Fallout 3, I am totally lame, and end up dying even on easy difficulties.
Has someone with the same problem published a guide that I will be able to follow and improve myself?
