computer games addictions !!

Computer games ! The main problem why I am unable to concentrate when I am doing my work. They are just so addicting . The colors , the movement of the characters you are controlling is just simply too real for a game. Technology has really improved a lot over the years ! I could still remember 5 years ago I am still playing games like runescape and neopets  ! But now games look so realistic and real, it reallys allow the players to be able to feel the game. I wonder how much technology can improve over the next 10 or even 20 years?
