I find that I've lost almost all my enthusiasm for roleplaying gaming of late. I think it might be time to take a break, certainly from GMing, and probably from playing as well. It's been coming for a while, and now it's here.
I doubt very much that this will be a permanent state of affairs; I've had this sort of burn-out before and come back from it. For now though, I just can't really be bothered.
