4 hours in means you're still in Norway, right? I'd give it till you get to England before giving up on it.
Yea in England is where things get really good. The is the issue I had with this game, while Norway did have beautiful mountains and scenery, it felt like a large land of nothing. Add that to the slow build up and I can see why a lot of players give up on this game early on. Of course it doesn't help that a good chunk of these players are coming in from Odyssey where the landscape was the complete opposite of that.
I also think the setting sort of matters too, you need to enjoy the Viking mood in order to enjoy this game. I personally love ancient Greece, and that was part of the enjoyment factor in Odyssey. With the Vikings, I didn't care too much for until I started to watch the TV series and read more about them, and that was the biggest factor in me giving this game another shot.
