| TransportSame idea | Carriers walk every good, one at a time, between buildings and stockpiles. | Freighter ships fly every good, one chunk per trip, between planets and stations. You can follow every run. |
|---|
| Production chainsSame idea | Wood, stone, ore, coal and food feed smelters, smiths and the army. | Ice, sand, minerals, grain and sunlight feed smelters, factories and shipyards. |
|---|
| Feeding the minesSame idea | Miners need food, so farms, fishers and bakers keep the ore coming. | The Iron Mine runs on Grain. Starve the Fields and the ore stops. |
|---|
| Stores and prioritiesSame idea | Each building buffers a few units of every good; you set transport priorities and how goods are shared out. | Each building buffers up to 8 chunks of every good; you set goods priority and the split between construction and production. |
|---|
| TerritorySame idea | Garrisoned towers and castles push out your border; lose them and the land goes with them. | Crewed Towers project your border; kill the crew and the border collapses. |
|---|
| PeoplesSame idea | Each people builds in its own style, with its own soldiers. | Three empires, each with its own architecture, its own hulls and one ship nobody else can build. |
|---|
| SettingDifferent | Ancient and medieval lands on a tile map. | Star systems: planets, asteroid fields and orbital stations. |
|---|
| WorkersDifferent | Every building needs a settler, often with a tool, before it runs. | Buildings run on their inputs alone; ships do the carrying and the building. |
|---|
| Raw resourcesDifferent | Foresters replant trees; ore seams run out. | Each asteroid holds 40 chunks and runs out; planet sources keep producing. |
|---|
| CombatDifferent | Swordsmen and bowmen fight on foot. | Warship fleets fight in real time with lasers, plasma, melta and missiles, and earn bronze, silver and gold ranks. Freighters are never targets. |
|---|
| How you playDifferent | A PC game you buy and install. | Free in the browser, with no install and no account. Multiplayer runs peer to peer. |
