If it was a side quest for Gothic 1, I wouldn't say a thing...
Second thing that puts me of storyline and classes, it all the same story as in all 3 Gothics, same factions same story, same path. Nothing new.
Third thing dialogs; who writes them? Really, my 10 year old nephew could do better.
Next thing is fighting, omg that is really the weakest point in the game, the only intelligence that mobs have running around you, with tactics that you can work out in 5 seconds. Unless you are being attacked by more that 2 mobs simultaneously, there is no way you gonna die.
Summary: you get the feeling that the game has been created in 2 weeks, using some ancient engines and scripts that they found in the archives of Gothic 1, and in my opinion the only purpose of this game is to earn some easy cash and keep us occupied until they finish Gothic 4.
