There are more wolves out at night, or so it seems to me. Great when hunting and ready for a fight, not so much at other times.
What impresses me are the atmopherics, they've done an amazingly good job with the weather. My particular 'faveorite' being a thick mist coming up just as you approach a Fuling camp... 'oh goody' I always mumble, just before backing away slowly and quietly.
Two things that really irks are the inability to open a door or chest when using a tool (a mod fixed this), and the inability to take refined metal through the portals that do allowed implements made from refined metal. I just cheat-spawn* as frankly I want to have fun when playing a game.
* On every map I do things properly the first time, eg finding, mining, transporting silver and black metal. After that tbh 'life's too short', and besides, that new camp/farm/castle/cabin won't build itself.
