I wouldn't say that Drakensang, Gothic and Loki have much in common, except that they were developed in Germany, and I don't even think Loki was very successful in Germany. German games will perhaps not as easily become an international success as US games, but that's probably also true for French or Italian games ... and it's the same with movies or music (even English-language music from non-English-speaking countries).

Sure, div2 was published first (and successfully) in Germany, but unless you're implying Germans generally have a bad taste with respect to games, I don't see why this should mean it's just a mediocre game.

The lack of a big international media coverage is not very surprising for a game from a small or medium company that will only be published in two or three months (English version). Even if div2 were a bad or mediocre game, most magazines wouldn't simply ignore it, but give it bad or mediocre (p)reviews. Have you found any? If not, it's maybe just too early.

On the other hand, I agree that the information policy for div2 does not seem very clever, whoever might be responsible and even if you consider that it's quite common for games companies not to stick to their target release dates.
