I suspect I am a victim of Game Attention Deficit Disorder, GADD for short. My problem is that lately I am finding myself jumping from game to game. I am unable to spend enough to time in on e to even come close to completing it before I am pulled into a different game. In the Last two months I have played.
WoW
Puzzle Quest
Assassins Creed
Mass Effect
Hell Gate London
EQ2
Pirates of the Burning
Neverwinter Nights 2
Team Fortress 2
City of Heroes
Several XBLA demos and PC casual game demos
As well as created characters for 2 play by post D&D games.

Now yes I had played WoW for many months before that, and I did complete AC and ME so I have not been a complete flake but I remember back in the day when I would play one game for a long time before I started another. Of course back then there were not nearly as many good games as there are now. Well, the first step to dealing with a problem is to admit you have one so yay me for taking the first step.
