Arnaud shared some of the toughest parts of development, which were the pressure of creating a world vast enough to entertain players for months (and now years) and ensuring that everything was as stable and functional as possible from a technical point. He followed up by reliving the joy of a successful launch and the success that the game met with over time. He talked a bit about updates and DLC, which come out every one or two months and are generally still drawn from the original design document for Order & Chaos: Online, given that the world design was much bigger than could possibly fit into the game originally.
Bonnard also addressed the server separation between Android, iOS, and Mac devices: Not only would it be time-consuming to link all the operating systems, but such a system would mean that patches could only be deployed once every device was supported, which would be tricky and cause too many extra delays. As far as Order and Chaos' future is concerned, he's optimistic. There are new graphic features coming down the pipe as well as "lots of ideas for the game" as the company looks forward to another fantastic year thanks to fan support.
