Hi @The Pilgrim, don't be worried about the ~1.7k science per turn - as that number may be a show off (e.g. perhaps relying on reaching globalisation, and getting +10% science per city state) - so these outputs are only valid for the last few turns. Its also Aztech on a very favourable map - so not really representative of other T140 victories. So, being around the 1k mark is good for end game for a T140 victory - although - its also important to start generating large amounts of science as quickly as possible. The obvious key thing is - getting all campuses out as soon as possible. Then getting libs/unis - Now the more you have - the more GPP you get. This will allow you to hit one or two GS that give increased yields to campus district buildings (eg +4 science per university - which doubles to +8). If lucky you can get two. Another thing I do is - once city is considered 'built up' (e.g. has a uni/lib/cd or whatever i was planning to get there) - i assign the citizens to work as specialist (adding +2 or +4 science) per city. Hope this helps.
