Minerals eveywhere is bad, Bugs the detecter somehthing fierce.
Uh, okay, you know how, in adventuer mode, you can prioritze an enemy or a enemies body part, or use a particular escape route or strategy? and even when your companions do stupid stuff like charging at wildlife, at the very minimium you could sorta keep them on track, or at least, be the one doing something right?
Dwarves don't do that, compadre. You're on their own. A third to a fourth of everything you do will be keeping dorfs from killing themselves as quickly and as efficiently as concievably possible. Trust me, everything you tell them to do, they will misinterpret to the highest possible degree. It will be this pervasive atmosphere of utter failures that make sucessful dwarfs so cherished.
At the same time, there is a united force of chaos, goblins, zombies, badgers, Clowns, you name it, But they are all united singularly in the cause of bringing you, and your troop of incompetent dwarves, to your knees, then cutting them off and beating you to death with them.
One of the last problems is you. In adventure mode, mistakes can be erased. Injuries heal, new companions can be recruited, you can turn into a werewolf. But here, a critical mistake becomes a living thing, seperate onto its own. You can't just walk away from the magma spilling out,or the badgers coming, you're stuck, and they know it. A single mistake could collapse something, like a accordian. Forgot to make clothes? Everyone everywhere beats each other with their fists. Aquifer piercing failed? Well, that section of the fort is now the swimming pool, inhabited by the corpses of your dwarves, reminding you of your failure, and of your impending doom. Gennerally, here, your mistake will live on like a scar, but worse, and deeper.
You find these things difficult seperately, but together, they are unstoppable. In adventure mode, at least you can always manuver into a corner, or run away. Your dwarves don't do that. They will stand in the corners of the map, just begging a ambush to claim their soul. A flood of magma will send dwarves fleeing, unless their napping in the hall, in which case their !!*dwarf roast*!!. That cavein of your walls will be timed at the same time of your biggest siege ever, with the demon leader in tow. You are at their mercy. But moreso, you're at the mercy of alcoholic midgets incapable of intelligence, fighting against the siege with whatever weapons and defenses you planned and they manage to put into action.
All you can hope for is that all your plans were't for naught.
And that the siege operater gets back from drinking in time.
Also, medium savagery is best, provides more food.
Oh, and watch out for your FPS.
