Brief overview

• Dozens of hours of work, thousands of new files, numerous tweaks and minor changes, most of which will probably go unnoticed
• To make the game slower paced and encourage keeping your units alive, all unit training times and all technology research times are aproximately doubled
• A new resource: silver (see below)
• Warships, mercenaries, champions, and several structures consume resources (see below)
• Heroes and ships require 0 population
• Women can no longer build, but can gather resources
  • citizen soldiers and slaves can both build and gather resources
  • mercenary soldiers can build, but can no longer gather resources
  • champion soldiers can neither build nor gather resources
• All soldiers cost at least some metal to encourage feminization
• All soldiers have their attack rate normalized to 1 second
• All soldiers (citizen, mercenary, and champion) can advance in rank:
  • instead of basic/advanced/elite, units start at rank 0 and can promote a dozen times, up to rank 12;
  • each rank grants +5% health, attack damage, and capture strength
• Camelry, chariotry, and elephantry are now distinct classes, separate from cavalry; as a consequence, they no longer benefit from cavalry technologies
• Cavalry, camels, and worker elephants can no longer be trained at the civic centre or crannog
  • women can be trained at houses by default (no longer require a technology to be unlocked)
• Loot resources are standardized to be equal to 20% of total costs for structures; units no longer grant loot
  • 0: fishing boat, merchant ship, support units, and most structures
  • 10% of maximum health: army camps, centres, fortresses, outposts, towers
  • 20% of maximum health: warships
  • 50% of maximum health: siege weapons
  • 100% of maximum health: heroes
  • 30 (base) + 3 per level: dogs
  • 60 (base) + 5 per level: infantry
  • 90 (base) + 8 per level: camelry
  • 120 (base) + 10 per level: cavalry
  • 240 (base) + 20 per level: bigae
  • 300 (base) + 25 per level: quadrigae
  • 360 (base) + 30 per level: elephantry
  • champions have +200% base loot experience
• Economic buildings and walls can be constructed in neutral territory
• All walls and towers are stronger and more expensive;
  • palisades and outposts are available in village phase,
  • outposts can be upgraded individually to sentry towers in town phase,
  • turf walls and sentry towers are available in town phase,
  • sentry towers can be upgraded individually to stone defence towers in city phase,
  • stone walls and stone towers are available in city phase;
• Phase advances no longer increase citizen soldier health nor metal gather rate
• A third level of infantry and cavalry armoury researches is available; blacksmith can be constructed in village phase
• Walls, storehouses, markets, fields, farmsteads, and corrals can be constructed in neutral territory (new), as can centres, crannogs, docks, harbours, shipyards, and outposts (unchanged)
• All units are bribable (espionage: temporarily reveal their vision range)
• Conquest critical are:
  • all units except fauna, women, fishing boats, healers, merchant ships, slaves, and traders
  • all military structures, centres, crannogs, fortresses, palaces, and wonders
• Trade gain now depends on x+x^1.5 (instead of x^2), with x the distance between markets

Soldier types

• Infantry can attack anything, can capture, can build, can gather
• War dogs can not attack elephants, ships, siege engines, or structures; can not capture, build, or gather
• Cavalry can attack and capture; can not build or gather
• Camelry can attack and capture; can not build or gather
• Chariotry can not attack structures; can capture; can not build or gather
• Elephantry can attack and capture; can not build or gather

• Champions are indicated by an arrow
• Economic units (women, slaves, support elephants, land traders, merchant ships, and fishing boats) are indicated by a rhombus
• Healers are indicated by a cross
• Other units are indicated by a circle

Phases

• Each phase increases centre building time, health, experience, territory influence radius by +20%, and resource trickle rate by +1 silver per 7 seconds
  • Centres cost by default 300 food and wood; 25 m and 50 m auras enabled
  • Village phase increases centre cost by 300 wood; 75 m aura enabled
  • Town phase increases centre cost by 300 stone; 100 m aura enabled

Silver

Silver is the new resource number one; it can not be gathered directly, but can be acquired by:

• selling resources
• traders (gain is currently any combination of silver and other resources)
• resource trickle rates (see below)

• looting structures:
  • libraries grant 100 silver
  • lighthouses grant 60 silver
