Rob Pardo, the chief creative officer for Blizzard Entertainment, is leaving the World of Warcraft maker after 17 years with the firm.
"Goodbye Blizzard! Thanks so much for the opportunity to contribute to the games we created together," Pardo tweeted alongside a link to a Battle.net blog post.
"Every ending is a beginning and today marks a new beginning for me," he wrote in the blog.
"After 17 years at Blizzard, with long and careful contemplation, I have made a difficult and bittersweet but ultimately exciting decision to pursue the next chapter in my life and career."
He continued: "It was a dream come true when I was given the opportunity to work on StarCraft, which at the time was being created by a very small team by today's standards. It was tremendously fulfilling to get to know everyone on the team personally and to contribute our energies toward a shared goal in such a creative and engaging environment.
"Blizzard Entertainment has been simply the best place in the world to be a game designer. The best aspect of designing games at Blizzard is that the entire company is passionate about the gameplay within each and every product. From the executive team to customer service to our global offices, every single person is a player and contributes to making the best possible games. It's for very good reason that the first credit on every Blizzard game is "Game Design by Blizzard Entertainment."
"I'm really proud of the contributions I was able to make to Blizzard's accomplishments. From building lasting games, to supporting the growth of eSports, to extending the Warcraft world into a feature film, and of course to being able to celebrate our shared passions with the Blizzard community online and at BlizzCon.
"The Blizzard community is ultimately the reason why we come to work every day and pour our souls into every world and experience we create. Blizzard's players are the most passionate in the world and your commitment and dedication are truly awesome to behold. Creating entertainment for you has been an incredible opportunity, and I know that you will continue to grow and become even stronger as a community over the years to come. It has been so meaningful on a personal level to help create joy for all of you.
"I'm looking forward to new challenges in my career, but I will always cherish the time I spent with you all and the amazing and collaborative teams at Blizzard. It was both satisfying and humbling, and it made me a better developer and a better person. I look forward to playing Blizzard games as a player for many years to come. Most important, now I have plenty of time to learn how to build a competitive Hearthstone deck."
So what's Pardo up to next?
"As to what I will be doing next, I don't have an answer for you yet . . . but I will "when it's ready." My priorities are to enjoy the summer with my family, play plenty of games, and think about what's next. The game industry is such an exciting place right now with PC gaming thriving, the new consoles, mobile games, and virtual reality becoming an actual reality. It's like having an empty quest log and going into a new zone for the first time."
