I think oni should at least give a nudge to the player what can he do.
Not things like : get steel, make at+st heat deletion, etc. I am talking about teasing the creativity of the player. By that i mean a bit of text with the buildings like : this cute machine does the job but couldn't it be done better or more efficient or whatever in some other way? Just to imply there are better ways if you are willing to risk failing and learning in the process.
I wouldn't really mind some buildings with a loss of material in some cases. Just so you can do it until you figure it out. But yeah, some people might just accept the loss and not try to build sth, which is what the game is all about IMO. Alas you will never be able to please everyone
P.S. radioactive puke in DLC or I'll riot
