• three phases: village, town, city
• four damage types: crush, hack, pierce, thrust
• five resources: silver, food, wood, stone, iron
• six structure categories: base, civic, defensive, economic, military, resource
• eight civilizations: Carthage, Gauls, Kush, Macedon, Mauryan India, Ptolemaic Egypt, Rome, Seleucid Empire

Changes include, but are not limited to:

• introduced a new resource: silver
• pierce damage is split into pierce (arrows) and thrust (spears)
• most units and many structures steadily consume small amounts of resources (upkeep)
• removed loot and looter, because they favour the victors, who are already at an advantage
• increased unit training and technology research times
• a greater variety of aura range visualization markers
• disabled unit promotion, heroes, team bonuses; they might be reintroduced at a later stage
• all civilization bonuses and penalties are replaced with new ones
• numerous minor tweaks and balances, most of which will probably go unnoticed

(return to table of contents)

• attacks can consume resources (D2113)
• build distance restrictions apply to all players, so you can't build a centre right next to one of another player
• capturable foundations
• damage inflicted is randomized (from 50% to 150%)
• garrisoned units can occupy more than one slot (D2056)
• only silver can be obtained through traders (D1846)
• world population cap setting; each surviving player is then entitled to a 1/n share; e.g. a four player game with a world population of 600: all players have a maximum population limit of 150 at start; one player is defeated, the others can now have up to 200; then another is defeated, both survivors up to 300 (D2426)
• random maps the default (instead of skirmish maps)

(return to table of contents)

• centred the minimap
• support for displaying five resources
• right selection panel can display up to 40 items (instead of 24)
• apply modifications to template values based on entity owner instead watching player (D2054)
• entity panels (heroes, relics, wonders) now also show capture bar (D2047)
• minor tweaks to tooltips and other elements

The AI no longer gets a resource stockpiling bonus or penalty, but the difficulty level determines how much time it takes to train units, build structures, or research technologies:

• Very Hard: 50%
• Hardest: 71%
• Medium: 100%
• Easy: 141%
• Very Easy: 200%

(return to table of contents)

• foundations are capturable
• <BuildRestrictions/Distance> applies to other players as well, e.g. you can't build a fortress right next to one of a different player
• economic structures can be constructed in neutral territory
• dropsites are just that: dropsites; all gather technologies are moved to the forge, which is now available in the village phase
• walls are stronger but also more expensive and slower to construct; all factions have palisades (village), siege walls (town), and city walls (city)
• fortresses have a territory root, are purely defensive structures, have somewhat more health, but no longer train any units
• all factions have cavalry stables (village) and arsenals (town); most have separate economic docks (village) and military shipyards (town); many have elephant stables (city)
