I still have fun when I log in, and the shell I'm in is really quite awesome. I've just had no desire to log in the past few days. I had updated my alt's CC info no problem, but I don't really want to play on that char, especially when I don't have access to my main.
There's only one person from FFXI that I talk to outside the game, and I'm certain that we would continue to talk even if I quit, so there's really no reason for me to feel like I have to hang onto it.
