He is bit right about German to rest of the world attitude about German games. Gothic 3 was somewhat successful even without much marketing..
But on other hand, as I see patches, it will be ok to release it bit later.
One thing would be nice and good.. give it some publicy, bit of adds? If I wouldn´t like Divine Divinity, I would probably never noticed that this game exist. And I´m in country NEXT to Germany..
I think its sad that game like this (and those before) don´t get deserved publicy. Cause games from Larian are really good.
Ofc if that works for you (economical point of view), its ok..
PS: If you want and MUST play it and you are willing to sacrifice English dub, theres way to make German version to English (text only) one.

But I guess you are bit lazy to search net, otherwise you would know.. (cause I wanted to play game too, but I was bit more determined than you, I guess

)
