@D'Artagnan, I got antsy when there was no forward movement. It need not have occurred had you posted your intentions earlier. Standard SG protocol is 24hrs to get the save and 48 after that to play and post with additional time for discussion if needed, just so long as the team is aware of what is going on.
As it seems you are asking for advice in the partial(?) log posted I will respond that the Great Library is not the best building for our needs. Let someone else waste the shields. Little libraries, harbors for the coastal towns, some courthouses and a Forbidden Palace are needed right now. I know it seems counter intuitive but building the Great Library will do more to slow down the tech pace than almost anything else we could do. The FP could go in the City on the gold hill, or in the wealthier of the two central towns. The advantage of putting it in the city on the gold hill is that town seems to be our best commerce generator and I foresee Copernicus and Newton's in there in the future. It could generate a ton of beakers all on its own. Putting it in one of the central towns will help with shields, though, so it is really a matter of which one can finish it faster, I guess.
Good to se you back in the driver's seat.
