Maybe you should read properly too?
I didn't say they scrapped the game, I said they scrapped her work, the script, which is probably why they are redoing all the performance capture.
The engine that the game is running on has been worked on for like three/four years, you've seen how fast they can crank out levels. Two months from geometry to what we saw at E3 (obviously textures and some artwork can be used across multiple levels, but my points still stands)
I'm not saying the whole game was scrapped, they can obviously still use previously made areas, but you can obviously change the context of the locations and the reason why someone is there, or you can keep the location the same but simply change what the people say and do, IE the script.
I mean, it's NN who said they scrapped all of her story, not me!
