some questions over to Ubisoft and had them answered collectively by Stephan Winter, CEO of Limbic (the company that develops the game for Ubisoft), Julien Pirou (Writer & Designer), and Gary Paulini (Producer).
No, there will not be "always-online" copy protection! Buy, download, play, that’s it.
However, implementing Uplay is a Ubisoft corporate policy and Might & Magic X - Legacy will not be different from any other Ubisoft title. So yes, Uplay will be in and you’ll need to be online for ONE time activation.
As the game will be based on Uplay, the chances of it being available on GoG are fairly slim, as their policy is no DRM at all (if we’re wrong and GoG is happy to distribute the game, please contact us! : ) ):(
What is this
ONE time activation? Is this really only one? or EACH time you install the game?? Do they plan their customer install the game only ONE time?: Will it be a play-once-then-put-to-the-bin game?...
