Wonders help to generate great people. I generally group wonders according to what type of great people they generate (so I have a city with all GS wonders, another with all GE wonders, etc.)How are you all getting GS so early to help bulb to the Renissance?? I am about 150 turns in, and I haven't gotten a single GS except the one I got from Writing. Just curious...I am using a lot of the advice given here on this thread, but I'm not cranking them out that fast at all.
To answer your question about GS more specifically, the wonders which are important to get a GS are the Great Library, the Oracle, and the Porcelain Tower. The last also provides a free GS (which many people use to bulb into the Renaissance Era).
It is best to have a city with high production (could be the capital or the second city) which will build the Great Library and the Oracle early. The combination of both wonders should generate an early GS (assuming that another city hasn't generated another great person and delayed the GS by increasing the cost). This GS farm city should also have enough population and food to run scientist specialists immediately upon finishing a University (ASAP after researching Education). The PT wonder can be rushed by a GE either from the Haiga Sophia (probably built in a different city) or from finishing the Liberty tree.
If you plan to settle a few of the early GS, it is not necessary for the Academies to be in the same city as the wonders (although it may be beneficial). What is important is for the city with the Academies to have a mountain (for the +50%

The city which has the wonders to generate GS points should also have any amplifiers to great people generation. This includes a Garden and the National Epic.
If you are planning to settle several great people, it may also be a good idea to go for the Freedom policy tree. The +100% applies to every Academy
