Titan, the MMO positioned to succeed World of Warcraft, was allegedly canceled because Blizzard Entertainment wasn’t able to control its scope and ambition.
Reported by VG247, Mike Morhaime, co-founder and former president of Blizzard Entertainment, revealed this during a speech at Gamelab in Barcelona, Spain.
“We’ve tried really hard not to announce any games that weren’t ready to be announced, or we weren’t sure that we were going to release them,” said Morhaime. “Titan is an exception to that where we wanted it to be our next generation, our sequel to sort of World of Warcraft. We took a lot of our senior developers and put them on this project. And I think where we really failed was we failed to control scope. It was very ambitious.”
