The legend of Zelda always delivers amazing puzzles and adventure. Twilight princess is truly an amazing game.
Graphics: The graphics to this game are truly amazing. The dark spirit-like color when in the twilight zone gives a great effect to the area, and same with the more colorful graphics when not in the twilight zone. The enemies also have a nice look to them, and some foes can even have a bit of creepiness to them.
Story: The story line in this game is actually great. It has a deep adventure going in and out of the twilight zone, and discovering many surprises throughout the entire game. Sometimes it even makes you imagine what it would be like to be in Link's position.
And just everything else makes Twilight Princess such a fantastic game, such as the giant boss battles and the different sound effects that the enemies make.
If you're the type of person that likes a great adventure game, this is your game!
