The OP created the thread to ask what the new boost buildings did. The thread was over when the OP questions were answered in post3, then confirmed in post4.
I have added a new question, now that the OP had his questions answered. My question is simply to ask what is the point of purchasing said buildings, and how do those buildings add anything new or "exciting" to the game? It appears further discussion has been created from that point forward...but no real answers.
