I ended up caving and buying Starhawk at GameStop. I'm not a huge GameStop fan but they had so many bonuses.
Actually the best PS3/360 converter is 90 bucks. It's the one to get because you're going to need to switch the L1/R1 triggers on PS3 shooters to the better L2/R2 triggers on the Xbox controller.
you dont need to put any money down on amazon preorders. they dont charge you until the game ships.
you will have the option to upgrade to another limited edition on amazon. thats what they did with me when the halo reach special eds were announced.
amazon offers a pre-order price guarantee. If the price falls lower it will lock you into that price. So by pre-ordering UFC they locked me in when the game dropped to 49.99 at one point. They also throw in 10 or 20 videogame credits. That's when you pre-order. Wait for amazon to add a 20 giftcard bonus. nijaskrypek is right. You end up getting free games.
It's 14.99 on amazon for bluray version
