Sony wanted to focus on a different type of game and we don’t really fit with that. But we’re in a very good relationship with them. They stopped a number of games last year at Sony and we took back the IP rights and were able to continue to develop it thanks to the support of the investors. We were then able to sign the game to a publisher who’s portfolio is a better fit for the game.

 

We didn’t show the game last year, but we showed concept artwork. This project is not exactly the same, it is an evolution. The concept of what we had with Sony was different.

We probably won’t ever know what other projects were canceled, and we can only hope they have as happy an outcome as Remember Me and weren’t first party titles.

I am thinking this is because this game was originally suppose to be an ARPG. I am a tad disappointed that it isn't :(

I think this is Dontnod's first game and they needed a budget that Capcom could better provide.  Besides, Adrift was just concept art and renders.
