The Tetris Effect

I have experienced the Tetris effect. Not only did I experience the effect with Tetris, but also with another game, Fallout 3. I have dedicated so much time to Fallout 3 and was totally immersed with the story that I thought about it several times outside of the magic circle. I have even dreamt about it. I believe the Tetris effect is capable in most, if not all, people. The repetitiveness gets to our brain and we obsess over it.
