start a community fort and do anything and everything that the members suggest, without question (unless it's how to do it)?
This works great if you want fun, it works even better if you also give the leader a dwarven personality, and use that personality to build the fort around, and respond to anything that happens. Examples: claustrophobic leader demands all rooms to be at least 3x3, 4x4, some size, and roads/paths must be at least (Insert numbers here). Paranoid leader wants at least 10% of all dwarves to be military at all times. OCD leader must have all rooms to be symetric, including every ground tile and wall. Think of something fun for the fort, yet still fitting for a dwarf and in character.
So, you're asked to build a megaproject with magma, highaltitude, hostile creatures, and something wierd that has been requested? Sure, but remember, what the average dwarf would say,
"Safety? What do you mean 'Safety'? Safety is for elves."
