In een open brief van de president van Sony's online entertainment afdeling valt te lezen hoe Sony World of Warcraft een 'spectacular' game noemt en dat ze een voorbeeld kunnen nemen aan Blizzard.
Sony online entertainment is vooral bekend van Everquest II, een van de grotere MMORPG's op de markt.

"[...]
Now what's been interesting from our perspective is what really serious competition is doing to the online gaming space. World of Warcraft has come on the scene and is doing awesome. Kudos to Blizzard on what I think is a spectacular game. I've played the heck out of it, and I love it (as have many people here at SOE). To a game developer, having another game developer play your game is the ultimate compliment... so to the folks at Blizzard we say "Nicely done".

But don't think for a second that we don't see WoW as both a great game AND Blizzard as serious competition.

Personally... I'm glad they are out there. They keep us honest. They keep us focused and they force us to play with our 'A' game. They've certainly opened some eyes in our company to styles of gameplay that are different than we would have come up with inside SOE. I hope they're also opening up the eyes of other MMO developers that the 'old school' probably won't cut it any more. I'm glad that we went in the direction we did with EQ II because had we stuck with making an even "harder core" game, I think bad things would have happened. We need to be about larger scale mass-entertainment... because that's what online gaming is slowly becoming. Our games just need to be fun... and easy to get into.
