I play because you suckered me in BEazy.
Regardless, I play because I enjoy building my nation and my alliance but at its core its because this game is perfect for me. I can think about it as much or as little as I want. If I don't pay bills every day, no big deal. If I want to sink a night into not thinking about how much I have going in my real life I can work on new alliance programs. Every other game I've played has significantly penalized me for not logging on at least 4 times a day and for me that's the brilliance of this type of game. CN just happens to be the one I've invested the time into.
