"The great end of all human industry, is the attainment of happiness." — David HumeCommerce Research is one of the four technology disciplines in Rise of Nations. Commerce technology focuses solely on the player's economic status, and their efficiency - the maximum rate at which players are allowed to gather any resource. In addition, Commerce technologies give the player new build options, and access to caravans (used to create wealth)
Each level of Commerce technology:
- Increases the Commerce Limit for all resources, varying from +30 to +100 per level (excluding Knowledge, which is limited only by the game cap of 999).
- Increases the Caravan Limit by +1, allowing you to create another trading route. Commerce Level 3 allows Caravans to establish trading routes to cities of allied nations.
The first Commerce technology unlocks the Market and the Dock, the second level allows the colonization of new continents and trading of resources at the Market. The Dock, along with the first Science technology, is required for land units to move over water to reach and colonize other landmasses.
- Collect a Silk rare resource with a Merchant to reduce Commerce Research cost by 25%.
- The Dutch start with the first Commerce technology already researched (unless playing a Nomad or City Center Only game) and receive a 10% discount on all future Commerce research.
- The Greeks receive a general 10% discount on all Library research cost (except for Knowledge) and research 100% faster.
