I've done some variation of official or unofficial classic servers about three times since I quit it the first time around. I totally get it; it's got a pull that the more modern MMOs (and games in general, really) just don't have.
That said, I've been on a Guild Wars 2 kick lately, so I'll probably do a bunch of that this weekend. I'm also playing Gems of War in mobile-friendly situations. Maybe something else if I've got the time, but that will be chosen via Steam Library Roulette.
