"I like long walks on the beach, drinking gin, and nerfing paladins." - Greg "Ghostcrawler" Street

Greg Street (alias Ghostcrawler) is the Lead Systems Designer for World of Warcraft. He describes his role as so, "Systems design specifically is everything that is not level, story, quest or encounter design. My team handles everything from classes to mechanics to items to trade skills to achievements to UI design, and that includes the game balance."[2] His influence on the game is so pervasive that he is often the target of community wrath, but also very respected for the detailed explanations he gives for his decisions.

He co-hosts many BlizzCon World of Warcraft panels.

He was previously (1998-2008) lead game designer at Ensemble Studios for the Age of Empires series.[3] [4]

He earned a PhD in Marine Science from the University of Texas at Austin in 1996.[5]


From the BlizzCon 2013 US Press Kit:[6][7]

As the lead systems designer for World of Warcraft®, Greg Street oversees roughly half of the World of Warcraft designers, including the class, item, profession, PvP, and encounter teams. His teams also design the user interface for the game and handle all of the number-crunching and balance fine-tuning that powers the game’s combat and gameplay systems.
Greg blogs about World of Warcraft’s game systems and discusses a variety of gameplay topics on Twitter under the “Ghostcrawler” persona.

Leaving Blizzard announcement

So Long, and Thanks for All the Spectral Fish | 2013-11-27 20:12 | Ghostcrawler
You know that part at the end of raid night when the final boss is dead and you’re done handing out loot and everyone kind of goes their separate ways? Yeah, this is one of those times.

We just came off of a great BlizzCon. We had so many different games to talk about, and we were thrilled at the reception of Warlords of Draenor. It was great to meet or reconnect with so many of you. I love BlizzCon dearly, which makes it so hard to tell you that this will be my last one, or at least my last one up on stage. An opportunity has come my way, and I have made the very tough decision to move on from Blizzard.

I wanted to thank all of you for being a part of this grand quest. I have said a hundred times that having passionate gamers, including the angry ones, is a far better place to be than having a community that doesn’t care. You all care. Like us, you want the game to be the best that it can be. So I ask you to keep on providing your feedback. I promise (and I rarely promise!) that the developers care very much about what you have to say.

I’ll be out there, and I can’t imagine it will be that hard to find me.

Hugs, Ghostcrawler

P.S. No, you can’t have a pony. Or a moose. Or a mantis shrimp. Or a tardigrade. Or a crab. Keep trying though.

P.P.S. I play a Holy Priest.
