Well, pretty late to the party, so just going to go over the options before deciding:
[] [Recruit] Mass recruitment (+6 Martial, -2 Econ, -2 Econ Expansion, -2 Centralization, additional effects)
This option gives us a shot at evolving Quality of it's Own, relieves further Centralization pressure(we'd need to fix this with lots of New Trails next though), but is expensive to our Econ slots(in that we'd need a New Settlement to replenish it next turn).
It's necessary if we picked one of the more challenging strategies, I don't think we can drive them anywhere without this.
May cause Martial overflow once Economy rebounds, if we don't evolve Quantity of it's own
[] [Recruit] Smaller recruitment (+3 Martial, potential additional effects)
Going to need at least this if we want to go save the MWs.
[] [Recruit] Focus on the next generation (+4 Econ, -4 Expansion)
If we just focus on the center then this is all we need. Lots of room to work in.
[] [Strategy] Hold the center
Easiest strategy, but gives the Nomads room to snowball
[] [Strategy] Relieve the west
Harder, focusess on preventing them from getting much metal, but we know they've been looting metal off the TS already
[] [Strategy] Drive them south-east
Set the lowlands on fire again. It's a time honored strategy, if a difficult one. Only a Heroic Martial king could pull it off, but if it works it deals with all the problems at once
[] [Library] Evolve a random value other than Love of Wisdom
Wildcard, but a pretty huge one.
Hopefully it applies to Honor of Elites(since a Library triggered Honor of Elites advance is the most likely to move away from pure martial elites), but we know EVERY trait evolution tends to be the best thing we can get long term.
[] [Library] Free Study Metal (Guaranteed breakthrough)
Probably Case Hardening from our known materials, which is a step closer to steel.
Or we might get early Blast Furnaces which would make iron FAR cheaper to produce in bulk.
[] [Library] Free Study Tailings (Guaranteed breakthrough)
Discovery of sulfur and the like.
[] [Library] Free Study Forests (Guaranteed breakthrough)
Apiaries?
[] [Library] Free Survey (Guaranteed Good or better result)
More metal or luxury deposits.
Overall, the Guaranteed breakthroughs aren't so tempting, because with the Library we can take Study actions pretty cheaply and with huge bonuses.
[] [Boats] Increase size while maintaining portability
[] [Boats] Increase speed while maintaining portability
Both of these are good for counterraiding the Nomads. Portable Size is more important for us however, since being able to run lots of dudes up the small rivers allows us to have nomad mobility on water and treat them to being outnumbered anywhere along the river
[] [Boats] New design: Emphasize size
Useful if only there was anything at sea there.
[] [Boats] New design: Emphasize speed
Not sure why we'd rush for this.
And it turns out the vote is mostly already leading, but whynot
