Great Library seems like a good idea and a whole lot faster than getting to mathematics AND construction. GL will speed that right up. At this point if any of the civs asks me for technology should I give it to them? If they are hostile and especially close to us I think I should give it to them but what if they are pleased or neutral with us??? Not sure how to handle this area and since we have alphabet now.... Ok, go for chopping over the iron at this point to get those immortals out. I like the ethnic cleansing in Pasargardae and I'll try to keep the citizens in Persepolis much more happy than they are used to.
