No such thing as a "WoW Killer"

For years games have tried to claim the seemingly impossible title of "WoW Killer" and so far each challenger has been unceremoniously crushed. So what's the big deal about this concept?
Well first of all lets look at this from a financial standpoint, with over 10 million subscribers at $15 a month... not a small chunk of change. And that doesn't even cover the online store and micro-transactions. It's definitely a position that most game companies would do almost anything to get.
So there it is, the white-whale. A lot of games and game reviewers have tried to convince the world gaming community of ones superiority over WoW and it doesn't appear that it will end any time soon.

One of the newer challengers is Guild Wars 2. As one of the current leaders in the "micro-transaction pricing model" MMO's GW2 has a fairly strong following and a few tricks up it's sleeve in the form of different game functions. GW2 steps away from the accepted ideology of most MMO's and brazenly states that it has done away with things like the holy trinity of gaming (a party combination of established roles including; Tank, Healer, and DPS), Loot ninjas (people that join groups only to steal or "need roll" on absolutely everything that  drops off mobs), and the removal of expansions.

I know what you're thinking "Hold up, no expansions? No growth?! How the heck can a game stay alive with stagnant content?!". Actually that's not as hard as it sounds. ArenaNet (the developer for GW2) has said that there will be no PAID expansions, every month new content is released into the game, either in the form of holiday events or, the newly coined phrase, the "living story".
All this makes GW2 an incredibly fun and attractive game, but WoW Killer? No. If anything the reality is that GW2 is the alternative, the second person in a 2 party system. It appeals to a different group, that's all.
Truthfully, the only WoW Killer that will ever exist are the Blizz executives. The game will live for as long as they let it and in turn we the players are the ones who decide when it's truly time to let it go.
