Couldn't hope to notice, that gameplay look's more like original Dragons Lair and Myst style, than normal gameplay. If game really is more like cutscenes with reaction tests and few different plots, then it's no wonder how they can produce CGI graphics to game. Game is just list of CGI videos, not real time graphics.
I hope i'm wrong, because it would be nice to see gaming evolve to next level, but now I'm guite sure that HR won't do it. Instead it will bring back early 90's VIDEOgames to this era.
