Joi Ito is famous for many things, but one of them is coining the phrase, "World of Warcraft is the new golf" (he in turn gives the nod to Cory O, but anyway..). I'm in agreement, if you're talking about playing with people on the same side as yourself.
So, if you've been living on the moon recently, WoW has two sides: Horde and Alliance. Neither is explicitly good nor bad, but certainly Horde are uglier and Alliance are prettier (some would say. For the Horde!).
This means that Alliance outnumber Horde by almost 2 to 1. Most folk want to be pretty, it seems, and this has game implications but that's a post for another day. The two sides are at war, of course: on a daily basis, we're out to get each other.
Yesterday I went to see a buddy down at a certain large satellite-TV company. He brought some game dude friends, and perhaps inevitably, the talk turned to World of Warcraft.
"Alice plays..", said my friend.
"Oh cool," said one of the chaps, "what level?"
"A 60 lock on the UK servers and a 57 mage on the US servers," I said. "Do you play?"
"Yep. Are you Horde?"
There was a beat as we assessed this new data. I looked at him, he looked at me.
"/Spit", I said.
I think perhaps WoW needs to be added to the trio of things you don't talk about at the business or dinner table: politics, religion, income... and Warcraft.
