Technical overview for requested features

These are some thoughts for a feature rich mode. Don't worry, there will be a vanilla mode without all that fancy stuff just feeling as good as this famous 20-years-old game. So every fancy feature changing the gameplay drastically could be also disabled by users.


  1. ITEM: A description of the item
  2. COMPLEXITY: subjective evaluation for the complexity of the implementation
  3. AFFECTED ENGINE PARTS: core engine modules that needs to be worked on, e.g. renderer, API, converter
  4. IMPLEMENTATION STATUS: links to pull requests or dependencies
  5. MILESTONE: Which milestone this feature will appear in
Type Task No. Item Comp Aff. Engine Imp. Status Mile
GAIA G1 Dynamic change of weather, seasons, day and night. Influence on terrain & line of sight (LOS). could be influenced by players with monk/myth unit.
GAIA G2 Wooden buildings and other flammable material can be lit, fire spreads around your city. fire departments (new building) to extinguish fires or villagers need to put out a fire of with water from a well (new building)
GAIA G3 Wild animals can steal food from your farms and food resources
GAIA G4 Wolves form pack and act together, wander the map, circle around towns, get hungry and seek food (deer, villagers, wild boar, bear, etc.).
GAIA G5 Renewable resources such as trees and animals that repopulate. Forest regeneration or seeding.
GAIA G6 Buildings in later ages cost stone with possibility of deep mining stone. villagers can dig/mine natural resources.
GAIA G7 Better fauna (Tapir, Tiger, ...). Improved animal colours
GAIA AI GI1 Fish migrate and replenish.
GAIA AI GI2 Mercenaries could be hired on behalf of the player
Gameplay GM1 Roads on commonly traveled areas allow faster travel. Pathfinding would let the units stay on the road. Appearance and quality depends on traffic (matted grass, dirt path, etc.). Neutral to all players. Turns soft/regular terrains into roads, requires stone, does not work on irregular terrains; grants movement speed to all allied units + passive vision (like a foundation spots units walking over them).
Gameplay GM2 Bridges for connections between islands. Blocks ships, allows land units to walk on. Terraforming. Wooden and stone bridges with different hp.
Gameplay GM3 Canals: creates empty, shallow and navigatable water.
Gameplay GM4 Single units can hide/bunk in the forest, only visible to a certain type of unit. Garrison function with no symbol, you can lose your units if you don't remember them.
Gameplay GM5 New Unit: spies (can burn down your city), lame your production
Gameplay GM6 New Unit: monk ship on water to convert ships
Gameplay GM7 New Unit: transport waggon on land to slowly transport ships over land
Gameplay GM8 Villagers need sleep at night, die at work (New Building: Caffeine industry)
Gameplay GM9 GAIA and terrain interaction, e.g. flock of bird rises up from tree when tree is felled or many people approach, hearable sound indicator, players hear and see birds when someone comes to their woodline at home. Triggered rocks falling of cliffs.
Gameplay GM10 Relics have special abilities (AOM), bonuses for attack and range. Generated randomly. Maybe also rolling relics with ranged attributes to bring into battle.
Gameplay GM11 Bring Kings/Queens into battle for special abilities within some tiles radius.
Gameplay GM12 Building produces in loop (AOM) as long as resources and pop space are available. Useful for unit prudction and farms in mill. Indicator over buildings or somewhere in the GUI for loop production. Toggle reseeding on/off.
Gameplay GM13 Mills can produce sheep, cows, turkeys
Gameplay GM14 "Conversion is enabled by researching Faith. Before, monks can only carry relics and heal units.
Gameplay GM15 Buildings can be deconstructed to recover materials, slower than destroying. Leave a salvage pile behind. Salvage diminishes over time. Salvage can be collected by villagers at a higher rate than other resources.
Gameplay GM16 Buildings can be captured when damaged to 20% or less. Player who repairs over 20% owns the building. New units can be produced out of this captured building from 50% on.
Gameplay GM17 Attack/defense bonuses for some unit formations. Dependent on minimum amount of units in this formation. New marching formation with speed bonus but defense malus. Cavalry flanking.
Gameplay GM18 Researches only affect newly produced units. Old ones need to be manually upgraded/retrained at production building.
Gameplay GM19 Scale wonder cost to max pop, number of players and available resources.
Gameplay GM20 A new 5th "free trade" age where allies share resources and give each other massive battles.
Gameplay GM21 New unit: Lance Cavalry, run over units in defending formations
Gameplay GM22 Researches can be globally and locally applied. e.g. upgrade just units garrisoned in the barracks for less research cost; e.g. you need 3 pikemen for the battle now, but you don't want to produce them in the future in masses (see GM18)
Gameplay GM23 Units can level up by gaining experience doing what they normally do, fighting in battle against their counter unit will give more XP against that unit style. Villagers chopping a Forest Nothing map might be a real pro at chopping trees at the end of the game e.g. one experienced villager could be as productive as three unexperienced villagers in the end of the game.
Gameplay GM24 Queue for technology researches.
Gameplay GM25 Farms cannot be placed on desert ground.
Gameplay GM26 Improved water battles.
Gameplay GM27 Percentage based armor system similar to AoEO and AoM. Will need to rebalance whole gameplay.
Gameplay GM28 Entirely rebalance milita line. Main gold unit similar to knights/archers. Instead of a counter unit currently.
Gameplay GM29 Nerf the range on towers early and make them scale much better into the late game.
Gameplay GM30 Unit queuing doesn't block resources. Resources are taken in account, when the unit is actually starting to be produced.
Gameplay GM31 Make denying upgrades more easy, like in SC2. Often players will destroy buildings to cancel an upgrade in progress and gain the upgrade advantage. Maybe in a special mod with less hp for buildings.
Gameplay GM32 Possibility to put archers/ranged units on a wall/castle to get elevation bonus.
Gameplay GM33 Quickwalling: first XX% (variable percentage) of a foundation is walkable, setting for e.g. tournaments
Gameplay GM34 Mesoamerican civilizations (already the most novel civs in the game) may have a unique tech tree. Possibility for a unique tech tree in API.
Gameplay GM35 Controlled forest fires: Allows the player (technology researched at the university in the castle age) to destroy forests to create more space; this goes much faster/efficient than chopping, but obviously at the expense of the lumber and generates regular terrain.
Gameplay GM36 Give siege rams an upgrade that prevents unit production while it's attacking a building. (5-second debuff that refreshes each attack).
Gameplay GM37 Bigger maps, map sizes between giant and ludicrous
Gameplay GM38 Foundation: turns regular terrain into solid terrain, requires stone, turns irregular terrain into regular terrain.
Gameplay GM39 Different terrain types, take a look into for more explanations
Gameplay GM40 Be able to temporarily toggle the map to remove terrain and show building footprints for walling without gaps.
Gameplay GM41 Make rams push units away
Gameplay GM42 Raise the amount of ressources that can be sold with hotkeys at the market (forest nothing)
Gameplay GM43 A special flag that raises on a building that is researching a technology, much like the garrison flag. (see GR10)

Pathing PA4 Allow setting any number of waypoints (basically an extension of the 'patrol' mechanic)
Pathing PA5 Formations and movement when attacking.
Multiplayer MP1 Finegraded options in Lobby-Settings (e.g. formations, allow/disallow functions). Vanilla mode to have them good ol' feelings. Disallow also units and buildings, e.g. bombardtower, walls, etc.
Multiplayer MP2 Boosts/handicaps such as resource multipliers for players

Multiplayer MP15 Multiplayer mods looking for smurfs, trolls, racists to ban them.
Multiplayer MP16 Game modes, See
UI UI1 Organizers can manage the whole tournament in the openage interface within their accounts. Drafting, (Time-)Planning, Invitations, Promo, Hosting.
UI UI2 Multiplayer submenu should give you relevant information about most viewed live games and caster channels, upcoming tournaments, upcoming qualifier rounds.
UI UI3 Spectator layer for public watching. Lock to casters viewpoints or freely move camera. Chat with spectators and mark points of interests (POI) on the map. No sync needed. Spectator dashboard.
UI UI4 Casters interface: Picture-in-picture mode and replay function (command for making a clip and queue it). Pinging on minimap. Marking POI. Casters views need to be synced. Show casters current camera positions on minimap. See which units are visible to players without FOG. Second window for casting preferences and overviews. Caster dashboard.
UI UI5 APM should be derivable for interfaces and also be show in the GUI.
UI UI6 Customizable hotkeys for everything. But good hotkeys from the beginning.
UI UI7 Help spotting units which are target of a conversion. Highlight monk and unit.
UI UI8 Better after-game analysis. Normal mode with the basic information. Advanced mode with a massive amount of statistical infos and easy to read diagrams for smallest things. Population graphs AOE3-style at the end of a match. Show number of villager kills and lost resources (villagers carrying resources), maybe even in-game (caster- and spectator mode).
UI UI9 Copy and paste for building structures, e.g. select mill and the farms around it, copy and paste the foundations of them somewhere else. Same for production lines. (Factorio-style)
UI UI10 Show research and production status in the top right corner to easier follow your running researches.
UI UI11 Show how many villagers are working on each ressource (like in AOM, 100 Gold / 4 [Villager-Symbol] --> 100 Gold in the bank and 4 vills working to mine gold).
UI UI12 Add resource gain per minute data next to the original resources. It would be something like food: 537 (+68). make it switchable with amount of vills working at all the resource spots. (see UI11)
UI UI13 Hotkeys for technology researches and upgrades for units
UI UI14 All these things in here should be switchable-on/off in the options.
UI UI15 MP-GUI: game-browser in list-style but with HDs lobby filtering, amount of players? search bar for game names. better filters for games.
UI UI16 Save Camera positions: Ctrl+F1 to create a camera location hotkey similar to how you create control groups. Whenever you press the key it moves your screen to the exact location you created it. Also for spectating and casters.
UI UI17 Looking for a SC2-Interface in AOE-style? UI-Modding should be made easy.
UI UI18 Tooltips should be improved to properly showcase all the hidden information and bonuses for players who don't want to deeply research every facet of the game by themselves.
UI UI19 Host of lobby to ban civilizations, give handicaps
UI UI20 Idle villager button change colour when a villager goes idle
AI AI1 Handle units more intelligent.
AI AI2 Don't build in hazardous areas. Send military to clear out.
AI AI3 Better and more intelligent building placements, e.g. build more gates to prevent lock-ins. Better castle placement. Better market placements for trade in the late game.
AI AI4 Military units shouldn't fight in castle arrow fire.
AI AI5 Units marching react and don't just go away.
AI AI6 AI lames you (as the Barbarian AI). Understands how to do economic damage to your base. Adopts more to the current playing meta and also randomly choses to use older metas.
AI AI7 AI can deliver villagers with transportships to other islands.
Graphics GR1 Zooming in and out with different settings: middle of screen, where mouse points, to selected units.
Graphics GR2 Units throw torches to put buildings on fire instead of fighting against them with their swords. Villagers have different attack animations depending on where they were working before attacking units/buildings, e.g. farms -> hay fork, lumberjacks -> axe, stone or gold -> pickaxe.
Graphics GR3 Animations for construction and destruction of buildings.
Graphics GR4 Unique military and economic unit skins for each different region. Knights from Europe shouldn't look like the ones from Japan, but should be similar enough to tell they are both knights. At least 4 regions for unit graphics.
Graphics GR5 Beautiful weather effects (see G1)
Graphics GR6 Campaign cutscenes
Graphics GR7 Some graphical optimisations for competitive play by design, e.g. small trees, alignment grid, fish outlines, short walls, etc., other option: to redesign everything that the problems why those mods exists are fixed. e.g. make the look behind walls better by design -> no short walls needed.
Graphics GR8 Resource spots change size based on the amount of resource they have left.
Graphics GR9 Sync ram attack animation with the actual attack.
Graphics GR10 A special flag that raises on a building that is researching a technology, much like the garrison flag. (see GM44)
Sound SO1 Options to change the volume of special game sounds (e.g. attack bell, farm depleted, units produced). In late game this sounds can get really annoying.
Campaign CP1 Co-Op Campaigns
