Here is what it says
How many times can I download my game?
For digital games that you purchase from Amazon.com you can download them to as many of your computers as you like. Visit your games library to view your list of purchased games and to download them.
Can I install my games to other computers?
Each game manufacturer has a different policy on how many activations are allowed with each activation key. If you run out of installations for the activation key you originally purchased from Amazon please contact customer service and we will happily provide you with another key at no additional charge.
I am wondering whether I can buy a copy of battle field and put it on my 2 computers at home and have a friend play on one while i play on the other one. I think EA would require that we have two different activations if two different people are playing, but since amazon says they will provide another one, would i be fine?
i guess the question is will two people be able to play simultaneously with the same download.
anyone have experience with this? i have emailed amazon.
