I was addicted to Super Mario World on the GameBoy for a while. Beat it about fifteen times in a row before I got bored with it.
I think I don't have the attention span to become addicted to a game. I get bored, I play something else, I get bored, I play something else, I get bored, rinse and repeat ad nauseum, etcetera, ad infinitum.
Besides, I work at home. I have nothing else to do but play games
