Hello,
The game is probably not doing very well in Germany. For the time being, as the marketing is obviously not very effective, it is probably a cult game, with the people that stumbled upon this site and became followers

ordering quickly after release.
That would explain reasonably high sales at the launch of the game. Sofar however, no broad attention is given to the game in Germany. There seems to be only one website with a sort of review (and a bad one at that). Advertizing by Blackstar has not been wide as far as I can see, I found one commercial websitebanner, one advertisement in a game magazine, (no test of the game in that magazine though). As for those game magazines, afaik there have not been any thorough tests published, nor will there be in the december issues.
Quite disappointing. EU can still only be ordered at a small number of online shops. I don't know about the availability of the game in normal shops, but without press support it's not going to be a major Xmas winner in my view anyhow.
The only site that has EU in their top ten selling games is the games24.de site, which I and other people on this board have recommended after finding they offer a good (and international) service.
We will probably have to wait for the fans of the game spreading the word. Eventually, in my view, that will ensure rising sales, but it'll be slow going.
greetings, Oranje
