It's just in the nature of game developers to talk a little trash -- whenever you work on something for so long, you'll pretty much say whatever you can when someone asks you to compare your game to someone else's. So we'll forgive Funcom's Gaute Godager (game director of Age of Conan) for what he says about World of Warcraft in this Eurogamer interview.
WoW comes up first at the beginning of the interview, and Godager gracefully accepts props for AoC having the biggest launch since World of Warcraft. Which is true -- AoC has shipped over a million copies since launch (though Warcraft has gone on to sell nine million more, and AoC hasn't quite gotten there yet). But at the end of the interview, Godager really brings out the big guns -- he says that playing WoW is fun and all, but "if you've been to McDonald's for four or five years, and had your burger and your coke, sometimes it's great to just have a great steak and a glass of good wine."
Apparently Age of Conan is supposed to be that steak, and our little critically acclaimed and history-making game is supposed to be the culinary equivalent of McDonald's. Which isn't a bad comparison -- we can definitely see Age of Conan being called "steak." Especially since it was served so undercooked.
