Hey, guys, I am thinking very hard about whether or not to buy Sins of a Solar Empire Rebellion, and found out that it is $10 cheaper if you already have the original Sins game. However, on the website of Sins of a Solar Empire itself, I have not found a thing mentioning that or a spot to put in some sort of code of the original. so my question is: How do I get the game for less if I cannot find a way to put in a code of the original? My apologies if this sounds a bit scrambled.
