I have nevertheless continued to play and after a while it was fun. I brought each skill to 15 (from 100) and tried to battle everything from agriculture. In the end I noticed that but it will cost a lot of time to get into higher levels. Until 10, it went quite fast, to 15 it was OK but after that? In the forum I read from people who leave their character with hostile animals and then do something else, so he's fighting alone and get more skill points.
I have not played yet so many other good (solo) games I do not know at present whether I should go online here. I think I'll wait and watch the forums to see whether the promised improvements will also come.
