Hi there @maxdapro, I can take away your worries… there will be more than one kind of tree out there.
Within the KS-Video there should be more than one kind of tree visible and the developers already did state, that they want different kinds of trees and they should/might even have different uses like… ironwood likely will make a stronger wall than oak ^^
That was a kinda free quote from the developers as I not have the time right now to dig it up.
Edit:
ah yes… jumping back into the forum there was another threat… All about Trees
