I think his biggest issue there would be opportunities to speak the language. He understands it, as he didn't need anybody translating to him, I imagine its just a case where he doesn't like his heavy accent
Was that really fully planned though? I do remember he wanted a bit less dialouge, and an actor who could convey emotions using the face. But at the same time, there are recordings out there with truckloads of dialouge and lines that Sutherland did for MGS V that was cut out entirely for some reason.
I do believe he wanted less lines, but I also think there is slightly less than what was planned. Probably due to the development-problems.
Also, Geoff dropping by and making the best post in the thread is amazing.
