Thanks, Nintendo. A gift to the gamers.
TP is a GameCube game without a doubt. Its graphics and sounds (midi) are definitively from an other "era" but the game still looks and sounds great. The gameplay is fun -- althought the control scheme is rather similar to the GC version after all -- as you would expect with any Zelda game.
Twilight Princess is one of those games that astonish you, that you don't want to finish. Even with all the good recent games, no game since TWW can compare remotely positively with it.
