Game starts with a single (3rd tier) yellow constructor in player inventory.
Player cannot construct anything by hand.
Player cannot build or place any other constructors.
Additional Option called Eco Friendlier:
anything that 'burns' coal cannot be built or placed. (miners, inserters, boilers, furnaces)
player also starts with 2 electric furnaces, and 2 solar panels in inventory.
player will still have to progress through the standard tech tree to unlock them for later use.
I state build or place, specifically because I cannot recall if any of those items are used to construct other necessary items, so if they are required as ingredients, they can be built, but not placed. If they aren't ingredients, they can't be built at all. In the case of constructors, as the player has the highest constructor already, all other constructor construction is disabled.
