I sometimes think there is a slight confusion between addiction and immersion. If a game is good, the artwork makes sense, the lore is supportive of the gameworld and the interface isn't distracting, then a game can be very immersive. I've played some great games in my time, and the ones that I started playing at 4pm, only to look up at my clock and realizing that it's almost midnight -when it felt like I had only been playing for a couple of hours....I didn't become addicted in those 8 hours...I was immersed as one could become. I am of the opinion that the word "addiction"(as it applies to video games) should only be used when the activity intrudes into and starts affecting schedules, responsibilities and other important life matters. Much like drugs, gambling...etc.
