Has anyone tried any of the content mods? Golden mod, dark mysteries, noname, etc? From what I've seen, they all seem to be full of spelling errors, typos, mistranslations and bugs. Not worth it IMO.

Anyone have any good experiences?

Not many good ones, although some of the texture mods are okay.

The DirectX11 mod for Gothic 2 is pretty good. I wouldn't use it for Gothic 1 though. It's not ready at this point.

I played the English version of Dark Mysteries and I liked it. The English is ok and I don't remember any bugs. Another good mods are Diccuric and The Long Voyage Home. I never finished GoldenMod, so I can't say how good it is.

If you dont't ever played Dark Mysteries you should start now , it's in my opinion the best mod for this game .
There is a lot of new content and game system is more similar to this from gothic 2 for example in basic gothic 1 you have 3 levels of for example one handed ability in dark mysteries are % like G2 .
