I absolutely love this idea Since there are several kinds of tropic biomes, there’s different resources as well. So here are mine specific for a tropical rainforest:
Plants (sorry if already mentioned):
- Mahagony trees
- mahagony (for floors)
- Food from the plants
- Iron ore
I know some of the stuff is already in other biomes, but in a natural tropic rain forest these resources also are there. So maybe add them too, or not. At the end this biome shouldn’t be op.
Also in a tropic rain forest the areas dry out when there are no trees left. So when the trees are gone, there shouldn’t be water around anymore.
