In 2015 I purchased "Sins of a Solar Empire®: Rebellion Ultimate Edition" on GoG.
Now I see there is "Sins of a Solar Empire® - Ultimate Edition" being sold and my game links to it, but I do not seem to have everything the current page advertises.
When i look at the files available to download, I have part 1 and part 2 installation files, and then the rest is either patches or soundtrack downloads. I see nothing for DLCs or Trinity. Now I'm feeling like I don't really have an "ultimate" edition. So what's going on?
