"Since last year's financial short-coming performance of Square Enix Europe, we (HQ London and GM Eidos-Montreal) have had growing and divergent opinions on what needed to be done to correct the situation," D'Astous told Develop.
"The lack of leadership, lack of courage and the lack of communication were so evident, that I wasn't able to conduct my job correctly. I realised that our differences were irreconcilable, and that the best decision was unfortunately to part ways."
D'Astous was ousted from his leadership role during a Square Enix managerial shakeup in June, and was replaced by Deus Ex: Human Revolution executive producer David Anfossi. Following the corporate restructuring effort, Square Enix representatives told Develop that D'Astous had "taken on a new project in the company working directly with [current Square Enix head of studios] Darrell Gallagher across our studios focusing on cross studio operations."
