This could be a really cool concept for a succession game:
Goals:
1. Set up the main fort as a center for commerce, learning, and agriculture. In the mindset of a great city of old, the idea is to "build Rome in a day", as it stands.
This is complete when:
There is a main palace in plain view for most dwarves. It should be a crowning achievement, that would attract immigrants and be a symbol of your city- possibly dedicated to a god?
There is at least 1 statue garden with at least 4 statues.
There is a wealth of "leisure" items such as toys and instruments, soap, and such, either owned by dwarves or stockpiled in their rooms/large treasuries
There is a "wonder", something that makes your city proud, or the beginning of one- such as an artificial river in your fort or waterfalls
The population is at least 30.

Goal 2 is preparing. The threats from outside have grown troublingly strong and countermeasures must be made.
This is complete when:
There is a standing military, at least 10 dwarves
There is a subfort or panic room set up, with everything needed to supply 7~10 dwarves with what they need for survival for extended periods of time that can be shut off from the main fort
There is some form of trap + siege setup for a "frontline" defense
... Not entirely fleshed out past that.
The mechanics would also be slightly different than a regular succession game:
All dwarves, upon being found, are named after players. Anyone on the waitlist to play is named as soon as possible regardless of when they signed up to be named, but anyone can still be named.
The player plays until one of three situations is reached:
The player's dwarf is dead. If this happens before they get a turn, they must create a new entry at the bottom of the list (peferrably, someone not related to the original, but can be).
The player has played a year's game time.
The player's dwarf goes mad or is, for some other reasons, unfit to rule (such as a long hospital visit or jailing).
These are for story purposes, as it's quite Roman. Power struggles and chaos are quite prevalent, and there might be a mod for special Roman-themed things, such as lead-brewed beer.
