Why quote our outrageous Australian prices? Your implying people actually pay them instead of utilizing the many workarounds to get fair (read: Normal) prices.
The Darkness II – Pre-order was as cheap as $38.50 at GetGamesGo. Can only go down from there during sales.
Silent Hill: Downpour – ~$50 Perhaps from ozgameshop. Will wait for the price to drop on this one.
I Am Alive – $TBA, let’s roll with $20
Max Payne 3 – Let's assume $45-$50 On GreenManGaming, less if theres a promotional coupon.
Far Cry 3
Guild Wars 2
Again assume $45-50 or less at GMG/Amazon/GetGamesGo/Import
My list comes to what, $300 or so? A Farcry from the supposed $700 for the above
