I have only played a few hours yet. But I was a DM along time ago.
I would like to see some Role-playing elements that makes the world more alive.
Map- a nice big painted map over the world should be put in. Like Tolkiens Middle Earth map.
When you going to camp for the night a 1D20 should be rolled to determine how good campsite you find.
Weather and environmental features maybe. Day and night cycles.
Food and drink. Check out Vikings or Battle brothers.
Random encounters when you travel. 1D100 determine if you run into something.
Thank you
