So I suggest that you create rooms on the main lvls (not all
cause you will dig and find 1 lvl down or up the rooms )
These rooms can have:
-
Creatures / hostile underground cities
-
treasure
-
quests/forgotten monuments
-
the better tier resources not found on the sides of the
mountains (you`ll have to dig deep, be greedy)
The main reason I suggest this is cause dwarves:
-
would be boring if they only find stone and minerals
-
and they would be very protected in their mines in
comparison to other races
ps. I tried to build underground and they stopped building
as they had no space to move up
