The Gamecube version of this cracking game seems to be sold out everywhere, and is going for between £50 and £60+ on eBay - ouch! With Nintendo's track record of failing to give two hoots about UK gamers, I personally think it is unlikely that any more PAL copies of this game will be coming into the country.
DVDBoxOffice (great Canadian website) have it in stock now, ready to ship for $62.95 Canadian with free delivery - which works out at just under 28 quid! Bargain....!
Bear in mind that it is the NTSC version of the game, so you will need a NTSC compatible Gamecube or a Freeloader or Action Replay disk to play it over here. Freeloader disks are in stock at Amazon.co.uk for £8.99, plus delivery (eligible for free super saver delivery) if you need one. If you do have to buy a Freeloader then 'ta-dah!' you now have a multi-region Gamecube and can pick up loads of cheap NTSC games from the States/eBay. Can't lose really.
Anyhow, even buying this and a Freeloader from Amazon will cost you a maximum of £39 - still a big saving on the price from the eBay sharks!
Review of the game from Gamespy: "In the end, there's no way that The Legend of Zelda: Twilight Princess disappoints. It's an excellent addition (and homage to Ocarina) to the franchise, and you'll have an enormous amount of fun playing it from start to finish. It's an amazing epitaph to the GameCube's life and it's certainly the best game from Nintendo this year. If you've been on the fence in any capacity, then please rest assured that you'll not be disappointed. Nintendo's flagship game has arrived in style and you better damned well appreciate it. It's ultimately fantastic."
