Trade Resources in the Base Game
Bonus to Adjacent Improvements
Each trade resource on a planet provides an adjacency bonus to surrounding tiles.
Player Achievement Bonus
Each trade resource has a bonus associated with owning the resource. This is a global bonus that applies to your entire civ. The bonuses do indeed stack (despite the tooltip when looking at the resource saying "One Per Player") so owning 2 Precursor Nanites, for example, will give you a global +10% to your manufacturing on all of your colonies.
Note that if you trade a resource away to another civ and then lose your access to that resource, the civ that you traded the resource to continues to receive that resource until the number of turns expire, leaving you with a negative number of that resource. You do not receive any penalties from having a negative number of trade resources. There are several ways you could lose access to a trade resource:
- Destroy the trade resource on the colony screen of one of your planets.
- Give away or lose a planet to another civ.
- An agreement from another civ granting you the trade resource expires.
