Still waiting for a decent price on this before buying... some places are going over the top on prices, not paying £45 for a game :P
I think you might still be able to buy it through Amazon if you're in the UK, it's worth a look: Link
I'm not sure why the price is so high in Europe. I got it for $50 flat through Steam, preorder bonus and everything. Lemme know if you can use the American Amazon site, would be nice to know so I can point people in the right direction.
