I'm still playing, but then again I've only had the game for about 2-3 weeks now. I play with people I've enjoyed playing other games with (not just MMO's either) and I find the stories to be entertaining. In fact, I wish more MMO's did full voice acting throughout and not just leave you hanging with silent NPC's after the first island (looking at you Age of Conan).
I may go for another month of the game, at least. And really, other games and services send out emails similar to the one mentioned in the article. Maybe I'm just remembering incorrectly but Blizzard sends these out sometimes, sometimes with free game time, or offers of a free new pet as part of their various celebrations throughout the year. I can get a new pet if I resubscribe for this very particular period of time? Well alright!
