Oh OK then ^^
I'm not under the impression your wife understands very well what would be addictive factors in gaming, and perhaps it would be wise for you to explain exactly what game pattern are addictive to you. That she be stuck by the pair of word "original sin" is really odd to me, unless that was your kind of addiction?
I would have thought what usually drives addiction, on top of personal problem of course but that's you and not the games, could be stuff like endless MMOs (no end in sight, you have to grind the new raids to prepare for the incoming raids all the time), competitive gaming (FPS or Strategy games with a ladder), loot machines (like diablo) that resemble gambling machines.
She might want to learn the game genres, and not be fixated on their titles (which tell nothing much usually).
