During the Q&A portion of its earnings call today, Ubisoft CEO Yves Guillemot touched on Assassin's Creed Unity's disastrous launch by acknowledging it wasn't "perfect". That's one way to put it.
His full explanation, in response to an analyst question about how the company thinks Unity's problems could affect the future of the Assassin's Creed brand:
Each time there's a new transition of consoles, we try to create engines that take full advantage of the capacity of those consoles. In the case of Unity, we had to redo 100% of the engine. So when you do that, it's painful for all the group...and everything has to be recalibrated. With this game, a few things were not perfect when the game was launched. But the engine has been created, and it's going to help the brands to shine in the future.
