I don't understand why people get so mad when people compare new games to WoW. Blizzard may not have invented the mechanics of MMO gameplay but they sure did refine it to the point where it should be the basis of comparison for any game like it.
Here's an analogy:
Back in the day Sony took a $#!T on a plate and served it up as food and EA pissed in a cup and served it up as a drink and thats all everyone could eat and drink for a very long long time. Then Blizzard came along one day and looked at this mess and said I'm gonna use this stuff and turn it into something better.
So they take the $#!T and piss and turn it into furtilizer and spread it across their field and grow a bunch of vegetables, some grape trees and some grass for the cows to eat. In a couple of years they harvest everything they have grown and come to the table with a plate of steak and veggies and a glass of wine and people go absolutely gaga for it and its something that almost everyone wants.
Now many years go by and lots of people are happy eating their steak and their are even some $#!T still out there when a new chef comes up with a new plate. This chef comes to the table with some bacon wrapped steaks, veggies in spices and cream sauces and $200 Cognac.
Now all the steak eaters start drawing comparisons to how the new chef added stuff to their steak and veggies and whether the changes are for the better or worse. This vexes the $#!T eaters to no end and they scream and shout and stomp their feet claiming they were the first and their $#!T should be held in the highest regard and put at the top of the pedestal even though their creation was just broken down excrement of another plate of food.
Now which is the logical comparison?
