"We want to create a great game," said Blizzard COO Paul Sams to VG247, adding, "Something that's cool, and new, and different, and kind of next generation in terms of look and feel and gameplay. That's a challenging endeavour."

Blizzard itself may not yet know how different its game will be. "When we're building a new game from the ground up, what happens is that it's slow going for the first bit, while the team goes round and round and round figuring out how it's going to look and feel, what the player experience is and what the differentiators are," Sams explained.

"The last thing we want to do is say, 'Hey we're doing this,' and everyone says, 'Oh cool,' and then we change things completely," commented the executive.

Not much is known about the next MMO from the company that pulled 11 million players into its first one. Blizzard would neither confirm or deny that the game would be set in a new universe, although the studio does not intend to use the new game as a replacement for World of Warcraft.
