Speaking as part of a larger interview published, Reisberger commented specifically on Zynga, saying that he thought that the social giant was definitely trying to manoeuvre itself beyond the constraints of Facebook in order to grow.

"Oh they desperately want to," he said of the Cityville creator's desire to establish a separate user base.

"They have plans, they've had plans for the last two years. Everyone wants to reduce their dependence on Facebook I think. Eventually it will come, but as some attempts have shown in the past, it's not as easy to understand the world outside Facebook because it's a totally different world.

"That's why Bigpoint is in a very good position: we're not just the ones developing, we've mastered, to a certain degree, the distribution."
