I sincerely hope that game developer, and game team will or can consider making more trees, plants and grass for the game. As me personally feel that the game currently have limited trees and plants. Not much choices of trees.
And yes I do know, it is impossible to include all the the trees, foliage, grass in this world. As there are so many trees species in this world . I just hope you all can add on some more trees of the different biomes to the game
