Because they don't play it for the gameplay. I imagine there's a select amount of people out there, that like the 'style' it has, in regards to a MMORPG, but the primary reason people are into WoW, is the social aspect, which is true for nearly any modern MMO, it's just that under this premise, WoW attracts them even more.
It's no longer about being able to interact within a fantasy, and do battle with guts/glory and etc.
It's just a regurgitated bi-product of 'social acceptance' and the internet.
The majority of WoW type players, (and I say this without trying to sound like I'm being a bully or using a lame internet diss), literally, have NO life. And not because they aren't employed with a high paying job, or because they don't have a PhD in physics, or etc.; but rather that they molded their life and lifestyle around the virtual social world, as it's more 'understanding' and 'forgiving' towards them than the real world(you can see the same thing on internet forums and all kinds of similar internet related places, where people act as if they have 'friends' and 'followers' etc. because they enjoy the non-discriminating adoration and adulation).
As per the explination above, WoW would be the culprit in far more cases than something like CSS. Though you are right, essentially any addiction is bad.
It's a very sad state of affairs. It's a shame I don't run a country, I'd ban the fu**ing game.
