Featured in this video in-particular, we are shown a hub-world which the game will revolve around. You have traders who will sell you rare items and those who would also sell you better weapons to aid you in your fight. Quests will also be tied to these characters and completing them will open up new roads of loot to acquire. So as the phrase goes, you scratch their back and they will scratch yours.
