On the other hand, if you want to write a good paper about WoW here is my suggestion.
First, backstory: I actually did my university thesis on Personality and WoW. I posted it on here using a puppet. That was WAY back in the day before they popped up every 3 hours and caught aggro. I was one of those first few that made you think "hey, cool idea!" rather than "OMG another survey..." (or at least that's what I like to think).
I wrote my thesis on WoW and personality. I had subjects fill out a surveymonkey form that asked them 16 WoW-related questions about themselves and their WoW info (age, gender, most played "main" class, hours played weekly, etc.) and then had them complete a real 60-question personality test. (By real, I mean a professional test licensed by my university). I managed to get 1000+ completed surveys of which almost 700 were fully and properly complete. I did statistical analysis on the data to find whether WoW players, or certain interesting subsets of WoW players (I.e. females in their 30s, players with weekly playtimes 40+ hours, etc) differed from the general population. I honestly forget what my exact findings were, but it would be worth digging up ... Although I should mention the obvious downside: my survey was posted on multiple WoW gaming forums, so I got a population of forum posters/readers, not a genuine WoW population sample.
Anyway. There is one question I didn't ask in my survey that still makes me cringe when I realized I forgot it - What faction do you play?
If I had that information, I could have (in an amateur, but interesting sort of way) finally found some answers to the endless debate about the differences between Horde and Alliance players!?
Like are 12 year olds really more likely to play Nelf Hunters.
