Since you are working along the usual worldgen -> post w.g. -> adventure -> fortress cycle, which ones of the following features are more likely than not to make it to fortress mode (I'm basing myself off your devlogs since the last release):
1. Advanced romance (divorces, rejections, triangles, jealousy, simultaneous partnerships, remarriages, children outside wedding, etc)
2. Dwarven mounts
3. Visitor agents that are part of villain networks, and/or villain citizens
4. Plots to obtain positions (mayor, baron, etc.) or artifacts
5. Assassinations, kidnapping, theft, insurrection, tips for invasion as a result of these plots
6. "Intrigue skill" or loyalty being relevant and/or trainable
7. Sending agents of your own, capturing or killing the villain offsite
8. False identities for agents, villains and other non-vampire migrants/visitors
9. Advanced friendships (people becoming war buddies or childhood friends in your fort, or war buddies/childhood friends arriving together as migrants, etc)
10. Advanced crimes (corruption, embezzling, blackmailing, sabotage)
11. Athletic competitions
12. Appointable new positions (keeper of the seal, royal justiciar, master of beasts, etc.)
13. Foreign trading outposts, and/or being able to send trading outposts offsite
14. Prophets and/or priests arising from temples or arriving as visitors
15. Religion conversion, priesthood positions/occupations
16. Monastic orders
EDIT: to clarify, I'm asking about whether they'll be implemented in fort mode as an actual gameplay element, and in this upcoming release (or at least in subsequent passes, before the big wait, in one of the minor incremental/bugfix ones)
