4Prejudice is Alive and Well in the Game World
Like in any social environment, WoW has stereotypes. Of course the players can't see your actual race, but that's okay. You choose a race and class when you start the game, and you'll be stereotyped based on that instead.
For instance, you can choose to play as a Hunter. People will promptly refer to you as a "huntard" and start speaking to you loudly and slowly. Are hunters dumber on average than any other class? It's impossible to prove that kind of thing with hard facts or statistics, but yes.
It turns out a lot of new players and/or kiddies choose hunters when they first start playing (it's an easy class for the novice) so the "Hunter=Dumbass" stereotype was born and deeply entrenched in the culture.
Another class, Rogues, have a reputation for being assholes. Again, there's a reason for this. When playing against other humans, their most effective means of attack is to sneak up on people before they're ready, kill them very quickly, and use their abilities to run away before their victim's friends can get revenge.
Thus, players have figured out that many people select Rogues specifically because they enjoy this kind of hit-and-run behavior. Again we're not saying that all rogue players are bad people, but they are.
3A Whole Lot of Play Time is Spent Doing Things That Have Nothing to do With the Game
You would think that with raiding and guild duties and farming WoW players would be happy to have a free hour to sleep or possibly shower. Some manage to scrape the time together, but others take that free time as a challenge.
So, you wind up with activities like group dancing. In WoW, every player can dance, via the /dance command, and every race has a unique dance (male blood elves do the Napoleon Dynamite dance for example).
Druids can shapeshift, and their shapeshifted animal forms all have their own dances. Get a few dancing bears together, and everybody joins in, often leading to spontaneous dancing bear parades through the streets of a city, or massive dancing bear circles. Seriously.
Others spend time--a lot of time--coordinating group pictures, such as this masterpiece:
If you're not sure what you're looking at there, 25 or so players gathered around this shaft of light, summoned "mounts" (flying creatures) to fly to various heights, then all jumped off simultaneously so they could take this snapshot of them suspended in the beam, a split second before they all plummeted into a broken pile on the ground.
If that's not your thing, you can get a pet. Sure, WoW has companion creatures that will help you in combat and such, but others... they're just there.
"Stay. Good. This is a fun video game."
Some are bought, others can only be won by buying packs of the accompanying WoW trading card game until you get an extra rare card that gives you an in-game code for the pet. Some can only be obtained from attending the yearly WoW convention in Southern California.
And they're worth a lot of money. Not WoW gold, either. Real money.
These pets don't even have the interactivity of Nintendogs or Tamagotchis. They follow you around. They occasionally make noises. That's it. You can't pet them or feed them or tell them to do anything. But god damn will your guildmates be jealous when you show them what you did with your $750.
