I've gone through and read every single post in this thread. I must say I can understand why some people would be down and whatnot but think of it this way. Wherever you now live, if there was a major disaster what would you do? Would you just sit there and basically wither away or would you move out and try to rebuild?
I don't really have a "main" character but I had contingencies for if something happened to any of my characters. Most of it involved fighting to the bitter end and trying to gain a foothold elsewhere but come on.
What would you do when your main character gets to old to play? when you only get a few hours per turn and it takes a week to move from region to region? Will you quit then? If so weather you leave now or later doesn't really matter imho.
