anda live in Australia right? I don't know when it will be out there, but it's already out in Eropah and America. Maybe anda can just try via eBay atau a website that ships to australia. Anyways, I have already, and it's not really special. If anda expect a Grey's Anatomy Sims (I expected that) then you'll be disappointed. It's nothing like that.
I have already seen a Grey's Anatomy Nintendo DS game on sale in the UK. It was in GAME (www.game.co.uk). But i haven't been it anywhere else, although i haven't really looked... Have just checked the GAME website and there is a Wii version aswell, both were released on 13/03/09 - 13th March. They are onsale for about £17 at the moment - don't know how many $ that is.
