I don't exactly love this game. It's in many ways a step back from the previous ones, and it has a mass of problems, but it's still rather playable. What I am saying, is that there's something wrong with your priorities. Form follows function, and if you have a square kms upon square kms of flat plain to hold, you find the highest spot, and build a fort on that. It's not exactly some flash of genius solely made up by JRRT. Besides, this game has plenty of things that have been seen in previous games, movies and literature. But those games, movies and books had that kind of stuff too. Every form of art borrows constantly from everything it can. I find it amusing that this single issue now somehow broke the camel's back for you. And you seem to get quite worked up about it too...
There's a difference between borrowing something, or being inspired by something and stealing it.
That's like if one pop singer blatantly stole the beat and a large amount of the lyrics of one of their songs from a previous pop singer, and while everyone's up in arms about the plagiarism some dude comes along and says, "hey, every pop artist borrows from other pop artists, every pop artists steals their sound from those that invented pop." No. That is just stupid. You cannot create anything without it having similarities with something that has already been created, that is true, but creating something virtually identical to something else is not the same as creating something with similarities to something else.
Now I'm not saying Bethesda is plagiarising Jackson's work here, I'm not saying that at all, merely trying to point out that Bethesda clearly made Whiterun to look very similar to Edoras and they made Whiterun hold to look very similar to Rohan, it was clearly intentional and clearly an homage to Peter Jackson and Tolkien's image. This is obvious to everyone else I have talked to who has seen the film and played the game.
