Apparently, the company that made this had the rights to make a game based on the books, not the new line cinema films. So it was more directly inspired by the books. I remember borrowing it in high school for the GBA and thinking it wasn't bad. Wandering in Moria for ages. There's something charming about it and the graphics are more fairytale inspired which is interesting. If you google the PC version there's a lot of that early 2000s charm. Obviously most people would have played the EA published two towers game which featured events from the fellowship.
Is this the one where you start as frodo and have to use the ring somewhat?
