Another game built on being "Not-Aragorn", "Ain't-Legolas" and "I-can't-believe-it's-not-Gimli". They made an RPG just like this about 8 years ago now, it just shoe-horned your party into every scene possible from the movies. Even when it was physically insane, e.g. fighting the Balrog with Gandalf... On the bridge of Khazad-Dum... A party of four plus gandalf standing side-by-side on a three foot wide bridge.
I never played that, but was interested. Was it any good?
And while it looks like it's not based on any source material (that I know of), it could be interesting. Whether or not it's legit, that depends on how you look at it. Since it's based (however loosely) off of a book series, how far should they be allowed to go with taking liberties? Since I'm a big fan of LOTR, I would hope any game made based on it should have some reference in the books. Otherwise they are just making stuff up that was never envisioned by Tolkien, which I don't feel is right.
As for the mature rating, that could simply be because of bloodshed during combat. I'm not sure how much it takes to push a game into mature, but I didn't see anything in the video that really states WHY it gets a mature rating.
