I am interested in Portal 2.
"Which are differences"?
[PC Steam Key Only] (10 BTC)
[PC Retail Steam Game] (11 BTC)
The difference is- if you buy the key only version, you receive just the key. You activate the game directly via steam, on the lower left hand corner. You click add game, and type in the key.
With the retail version, you receive a physical box copy of the game in the mail. In the end, you still type the same key into steam to activate the game. It really just depends whether you want the box and DVD or not.
The reason the key code is 2 business days is that I am not holding stock on hand, I am rush shipping the retail version to myself, taking out the key, sending it to you, and then recycling the DVD.
I will try to make the EU console versions of these games available.
