I'm going to ask a question, and you're not going to like it. In fact, you may want to take a big chug from a pint of Ironforge's finest first. Go ahead, have a seat; I'll wait. In fact, I'll have one of my own.
Ready? Just remember, it's hypothetical, all right? Okay, here goes: What would you do if WoW shut down tomorrow? Say there were a huge natural disaster (but all the Blizzard employees made it out okay; I'm not cruel) and there was major data corruption and destruction, or perhaps the game just ran its course and is over. Either way, there is no more Azeroth, no servers or realms, no character list, not even a login screen or an annoying dragon roar every minute. What would you do?
Do you have another game to fill your time? If it were sudden and unforeseen, would you be angry about all your lost time and give up games altogether? Would you fill up the void with other technological means, with another hobby, or with family time?
I would probably spend more time writing, and maybe get some of these brainstorms colliding in my head down on paper. There are other games I've been putting off so I could concentrate on WoW that I could give a whirl. How would you fill your time?
