This was one of my favorite games growing up. I genuinely loved the sheer scale of the game. It was arguably more epic than anything I had yet seen as a child, and it's one of the best video games I ever owned on my old PS2.
Not to mention the all-star voice cast this game had: Elijah Wood, Gary Oldman, and Mark Hamill, to name a few. I wouldn't have known these names back when I played the game, but I still remember enjoying every second of the dialogue.
The music was superb, too, for a PS2 game. Just look up "Valley of Avalar" or "Floating Islands" or any of the rest of the soundtrack to see what I mean.
I'd love to see the whole trilogy on GOG so more people can experience both this and the other two games in the trilogy.
