So a percentage of people who play WoW identify with the core gaming demographic. A percentage of those people also play Zinga games. Therefore the Zynga is now catering to core gamers. QED.
Umm.......no? And who cares? Last I checked, there were, what?, eleven million people playing WoW? There's easily that many (if not way more) playing Zynga games. There are not that many gamers in world, there is bound to some overlap. And the implication that the "hardcore" gamers ONLY play "hardcore" games until Zynga is stupid. Long before Zynga came around, even "core" gamers were playing browser games on their breaks, or shovelware for their portables on the bus. Zynga is not winning over the "hardcore" demographic, they are just using a system that everyone uses (Facebook) that doesn't require you to be sitting in front of your TV. Considering the boom of "casual" games and the fact that many "casual" gamers sink more time into their social games then many "hardcore" gamers put into their "hardcore" games, at what point do you draw the line between core and casual? It can't be the types of games that are played (anyone willing to sink hours every day into Farmville is already pretty hardcore about it in my books), is it the mental effort that goes into it? How do you compare someone who dumps several hours a day into FarmVille with someone who hops into WoW, but only on the weekends because said person has a life/job/kids/whatever?
Is either of them more "hardcore" than the other? Does it even matter? To whom and why? Zynga shouldn't be focused on convincing the "core" demographic to buy it's games (and that is the only reason thee would release "statistics" like this), they should focus on making good games and on making their current games better. As long as they keep putting out quality products, people will play them. Otherwise, I find this information to be just noise.
