The thing is that there are many games that have excellent stories, it's the execution of the story the problem. The problem about making you care about a character in a video game is that those moments can be boring for a lot of gamers when developers try to interact those pieces. Not every game can develop that type of interaction and personally I would not want them to go in that direction.
Right now from ND body of work, they still have not found the solution because if UC3 is any indication, it was a polar game. Some people loved the linear what the story was told because it pushed them in the direction the developer could control and deliver a solid piece of story telling but others found it way to constricted, where going off script produced undesired results and made them feeling like they were in a interactive movie then playing a game.
I person probably will not get the next ND game if it goes the very linear route like UC3. Seeing all the action packed scenes were fine but actually playing the game kinda bored me because there was no real freedom.
