Mori_Yuki: Thank you for your reply!
Does this mean that this DLC also includes the main game? If so, you should update the store page description to clarify this. If the DLC doesn't include the main game, consider setting the price to 2.99 Euros, as GOG only allows owners of the game to purchase its DLC.
It's worth noting that you can gift a DLC to someone who already owns the game. With this in mind, it wouldn't make sense to keep the store price for this DLC at 20 Euros, instead of setting it to its original value of 2.99 Euros.
MetaPub: We will do our best to fix this issue.
Thanks for getting back to me and for trying to sort it out!
MetaPub: The thing is that if you own the game then you get 85% off for the 20EUR price level, meaning that you buy the DLC only for the DLC-only price. But if you don't own it then you purchase for the full price that is equal to full game + DLC
I understand, but once again, this doesn't address the real question and problem. :-)
Does this 20EUR DLC include access to the full game? From your response, it seems that it doesn't.
My core concern is that we can't purchase the DLC without
also owning the main game, 20EUR or otherwise.
So, even if the DLC alone costs 20EUR without an 85% discount, assuming someone purchases the DLC and ONLY the DLC for 20EUR, that person will still have to buy the FULL GAME for an additional +20EUR, and THAT is technically impossible on GOG. THIS is also why the 20EUR price tag for a single DLC is problematic, and that is why I suggested setting the DLC price to 2.99EUR.
