Although all famous buildings that you will see in Assassin’s Creed: Unity will be quite similar to the original; however, due to copyright issues, developers were unable to re-create everything as it is in real life.
The developers in a blog post gave an example of Notre Dame, saying that it couldn’t be re-created exactly as the original, but you will get the same feeling as you do in real life, when you see it in Assassin’s Creed: Unity.
There are certain things we were actually unable to directly re-create due to copyright issues. For example, when I look at the organ in Notre Dame, I think it’s a masterpiece. It’s just so huge and beautiful – and copyrighted.
We couldn’t reproduce it exactly, but we could still try to nail the feeling you get when you see it.
We kept it very similar in general appearance, and it’s only when you get close to it and really analyze it that you realize it’s not the same exact organ you would see in Notre Dame today.
Apart from the building’s exterior, interior has been changed as well to add multiple navigation options to allow players to roam around freely.
The wait for Assassin’s Creed: Unity is almost over, as the game is set to launch tomorrow for PlayStation 4, Xbox One and PC.
