This is a good deal for a Portal 2 pre-order.
Amazon is selling the PS3 version of Amazon for $54.99. If you pre-order it you will get a $20 credit towards items shipped and sold by Amazon. That basically makes the game $54.99 – $20 = $34.99! What’s awesome is the PS3 version is supposed to come with a Steam activation so you get the PC version free. So the PS3 version is definitely the way to go. I’m not sure how the activation process will work however. I’m assuming there will be some kind of redemption code that you enter into steam or a cd key you have to use.
I don’t think you’ll be able to buy the PS3 version and then sell the PC version. They’ll probably be tied together somehow.
The release date for the game is April 19, 2011.
Portal 2 – $54.99
EDIT: The game is also available for PC only pre order for $44.99. This game requires Steam.
