I was recently watching a 64 year old computer gamer try and play “Call of Duty: Modern Warfare 2″ on the XBox 360. It was not any fun for him by any stretch of the imagination and turning the difficulty setting down really did not help him much at all. On the easy level he did not die quite as fast but he still died far too often to get into the fun of the game.
We could go and give players longer to react to audio and visual cues but that would just make the game too easy for the rest of us and only partly solve their problem. Instead what if we gathered each individuals reaction times for the environment they are in. Then the game could auto tune for the individual characteristics of each human instead of making the bad assumption that they are all the same.
