Question Regarding Colonies

[RomanticGR]

Hello. Just a simple question do the rich resources stuck up ?  or you can benefit only from one resource of the same type.

No, bonuses of the same special resource type don't accumulate.
The same bonus granted by two different special resource terrains are accumulated.
If you have 2 colonies on rich gold field, you will have 10% gold income bonus. If you have 1 colony on rich wheat field and 1 on rich rice field, you will have 20% farm effect bonus.
