It isn't that great. Nordic is also the owner of JoWood. And they are responsible for faillures as Arkania: gothic 4 (was published under the nordic banner)
Nothing wrong with Nordic. They helped bring out a new version of D.W. Bradely's Dungeon Lords. It's the developers of Gothic 4 that you should look at, though I never tried Gothic 4 so I don't know how it is. And didn't Jowood put out Gothic 4, not Nordic? Nordic also puts out casual type games for consoles, I don't think Jowood ever did that.
They also published Europa 1400 and The Guild 2, which are some of the best simulation games ever.
Anyway, just saying they're not that bad.
Jowood is the publishing label of Nordic now, so Nordic is responsible. JoWood filled in for bankruptcy in 2011 and Nordic took over all assets of JoWood. Since then they use the jowood name as the publishing brand.
And most of the time the publisher is responsible for the quality of the game, as they are the ones who decides when a game is gonna to be released.
