It's not "essential" but I do wish TW cared more about immersion gameplay factors. Lack of feasts, bandits parties arbitrarily getting bigger depending on player clank rank (immersion breaking, awful for caravans), lack of depth to relationships/politics, lack of reasons to explore the very nice scenes, general lack of things to be doing outside of war war and sometimes WAR.
Like I said its not essential, but its disappointing that TW don't seem to care much about these elements that are the heart & soul of creating an immersive world that the player can get lost in. Hopefully the mod community can flesh out most of these aspects in time.
