NickLavic: So the soundtrack is required, that's a bummer. ... it sucks that I also had to buy the 10$ soundtrack to get the GOG Connect to work.
C'mon stay realistic folks! You get the ultimate edition so you need to own
all the content of the ultimate edition - no point of discussion IMHO
The game details also clearly state the contents in bold:
"Includes Sins of a Solar Empire: Rebellion plus the Forbidden Worlds, Stellar Phenomena, and Soundtrack DLCs"
also all the required appIds were posted quite often before the sale ended ;)
Steam connect is a good will offer from GOG (and the participating publishers) ♥ ♥
You already get your 50+ USD game a second time for free without any DRM huzzle, be thankful about the service offer - because why should they keep it up if people only whine and complain and causes additional work for them
Just my two cents, Greetz,
