They're both about equally addicting.
This is a serious question. It's like this game is impossible to quit forever. I haven't played in nearly a year and I still want to play the game every time I think about it. I don't have time for it, I don't even like it when I'm playing it, but I still want to. Exactly like cigarettes. So which one's worse? The one that kills you or the one that kills your social life and productivity?
