I repeat my statement that Bethesda releases most of it's games and DLC's in the places where they are sold most, first. Europe and the US bring in more income for gaming than the rest of the world combined.
/me scratch my head
I still don't see a conection. First, publisher in Eastern Europe is not Bethesta but 1C. Second, even if they would be publisher, why halt release of already finished product in other places?
Making DLC avaliable in English (most players will dl English ver. anyway) via Steam would not increase costs a bit (as DLC is finished, only translations for national languages aren't, which are local publisher job),and would surely increase income. I just don't see much sense in disabling ready DLC for anyone willing to pay for it.
Delaying release makes sense only in specific situations: 1. When game is to be sold in a box, which means translation is mandatory. 2. When due to local market circumstances price has to be lowered by a significant amount. This is simply to avoid shipping games from Russia/Slovakia/Poland where game is cheaper, to countries where gamers are charged a full price for same product. 3. When product is unfinished, and particular country works as "testing ground", and game, after patching, is released in other countries (not uncommon in Russia)
None of this is the matter here.
