I enjoy building my factories with the least amount of environmental impact -- call it a meta-game if you will. I find when using the chainsaw, it has a fairly large, 360 degree cutting arc that will very often annihilate a clump of trees when I really would prefer to be more precise.
Some suggestions:
1) Change chainsaw cutting to an 180 arc in front of the player rather than 360 degrees around the player.
2) or perhaps allow precision cutting with the Xeno-Basher
3) or provide a more precise Pruning Tool
4) or allow us to replant trees / bushes
Great game guys! Can't wait to see what you have in store for us.
