First, I should probably start by saying that the majority of what is said in this article goes for adventurer mode and adventurer mode only. With that:
In my opinion adventurer is going a little lifeless. Not in what you can do (especially with the upcoming patch), but what happens when you aren't doing anything. The sad truth is I cant wait to be ambushed by goblins or attacked by bogeymen, because otherwise there is no activity whatsoever in the world.
1.
Civilizations on break? Why is it that everyone is at home doing absolutely nothing? Shouldn't the farmers be farming on the fields at each town? Why arent the hunters and rangers hunting? Even if the farmer doesnt really obtain crops or the hunters never kills a animal, it would add to the liveliness of the game.
2.
Raids? It seems as the goblins and kobolds are always ready to jump on your back, but they never attack a town or village. When i say attack i dont mean a full-fledged siege (that would most likely destroy everything in world gen) but maybe just 3-5 goblins periodically attacking a village just to spice things up.
*Sub-suggestion: There should be a messanger. This way if a town is under attack, within a couple of hours a child will come running to you town to tell you*
3.
Professions? This is sort of a add-on to my first suggestion. When I get maimed or damaged in a battle, it would be great if i could go to a surgeon/doctor.etc. and have them do something. Im not asking for them to do something out of the ordinary, in fact, its less about the injury and more about having a interactive environment. Currently there are soldiers and commoners, because the professions mean nothing without individuality.
Like i stated, i understand most of this if not all will not be used for multiple reasons like it can open up too many exploits, it would make world gen insanely difficult, and just the fact that it would down-right crush your processors, but i thought iw ould just give a little taste of my dwarf utopia.
