Not like I'm trying to be a jerk, but this game shouldn't even be listed if it's not listed properly.
I should look into making games, can't be too hard. I have an immaculate attention to detail, something that seems to be completely missing from modern developers.
So, if someone buys the base game, and says wow I really like this, I want to support them, I want to give them more of my hard earned money, I want that soundtrack, they have 0 options except to rebuy the entire deluxe edition.
How does gog allow this to happen so often? The blame isn't solely on the developer, but a good developer wouldn't allow this to happen.
