Really good Tales game!
The idea of the collector's book, Monster list, and figurine book made the game one of my favourites. It became a game where you would get to the end, but you couldn't finish until you got everything (or at least as much as you could within one play through). Which brings up a good point, no matter how hard you try, you won't be able to complete everything on your first, or even your second playthrough. This is why I got hooked on it, knowing there is always an Item your missing, or a monster you don't have the stats of yet.
In addition to being highly addictive, Tales of Symphonia had a crew of characters everyone could grow to love, and added another amazing storyline to the game world. The game was my first view into the Tales world, and has kept me coming back to it.
