Go here, you can work it out from there
No 
It's not working.
When i click on "add to cart" it's always say next [ There are no items in your cart. ]
If the devs say they're actually going to do something about it, then they're going to do something about it.
I'm new here and i can't tell. You know, in most forum games, you can always dreams about changes even when they are promised. I'm not saying this about Sins, i have no idea, it's looks like the developpers are giving a good support and if it's the case, + 1 to them 
Reading about the pirate changes and the "invincible they are now" is afraid me from wanting to buy Diplomacy at all.
And the only thing i am afraid about the game in general are the common "minidump" things we can read all over the forum.
Anyways, he's right, the original game is missing from Impulse. There's Trinity, Entrenchment, Diplomacy, and the Entrenchment/Diplomacy bundle, but not the stand-alone original game.
Yeah
