This turn-based RPG should appeal to most Lord of the Rings or RPG fans, despite a few disadvantages.
You are given a large amount of skill development for each character, and can customize each one in a variety of ways. Different abilities can be advanced after each level up, and you can also choose what new powers you want to gain on each character's unique skill tree by using skills of that type more often. There is also a large amount of equipment to be found for each character throughout the game.
There are some downsides, however. Several parts of the game, such as Moria, will quickly grow repetitive and boring, as you fight the same enemies countless times. The largest downside, though, is a lack of character interaction, which is replaced by video cut scenes narrated by Gandalf, that explain what is happening, but take away from the realism of the game. Furthermore, the videos are just different segments from the movie pieced together. Besides these two problems, there is almost nothing negative about the game besides a few delays in game speed, and flaws in the actual Middle-Earth lore only the most devout of Tolkien fans would care to mention. And even then, I think they would like the game nonetheless.
