Yeah, I found that aspect of it really good. That rating I gave it? That was before I even finished the game. Since then I've grown to respect it and the people who made it even more.
See, a lot of people cry about how it's raping the lore and it's made by people just looking to cash in on the popularity of LotR without really knowing much about it, etc., and initially I thought pretty much the same thing (but didn't mind much because hey, it's a flipping video game, who cares). After playing through the game twice, I've revised my opinion. Yes, it's lore rape, but it's very deliberate, well-thought-out lore rape made by people who know a huge amount about Tolkien's world and are perfectly aware of what exactly they're doing to it. This is exactly what derivative works and tie-ins and such should be, IMO. It's respectful without being slavish, it explores the same themes and issues as the original work but does so from its own angle.
Ever notice how much Celebrimbor echoes Tolkien's own villains and antagonists? He wants to use the Enemy's own weapons against him, like Boromir. He wants to build an army of orcs to fight in Mordor, like Saruman. He calls himself the Silver Hand, mirroring Saruman's own moniker of the White Hand. Even the branding of the orcs with a hand print on the face is very similar. He bends this orc army to his will by outright enslaving them with mind control, much like Sauron himself bends his ringwraiths and other servants to his will. Remember how Galadriel said that yeah, she could take the Ring and defeat Sauron with it, but it would be a bad idea because she'd just be replacing one tyrant with another? Well Celebrimbor clearly has a different opinion on that, since that's exactly what he tried to do and he would have succeeded if the Ring hadn't betrayed him in much the same way it betrayed Isildur. He even echoes Galadriel's "all shall love me and despair" line with his own "all shall fear me and rejoice". The idea of ruling through fear is ever-present with him, he makes many remarks throughout the game about how all of Mordor will learn to fear him and such.
So yeah, this game is basically Spec Ops: The Line in fantasy land. You think you're playing a hero but you're actually not.
