Hey guys.I was wondering how can I make great person farm and is it worth it?
Yes, it's worth it, your GP Farm is probably the most important part of city specialization. The simplest way to pick your location is just look for the spot with the most food- grasslands, maybe desert floodplains, and as many food resources as you can get (especially 6

tiles like grassland pigs and riverside corn/wheat). The whole idea of this city is to grow it as big as you can as fast as you can.
You'll want to have your National Epic in your GP Farm. If I have the production there, I usually put Globe Theatre there too so I don't have to waste time making happiness buildings. Farm as much as possible of the BFC, don't bother making any cottages there. If the BFC has a hill or two you can mine them to get the

you need to build everything, then maybe later on put windmills there for more food.
As far as what to build there, focus on buildings that let you run Specialists (forge for Engineers, temples for Priests, library for Scientists, etc.) The Specialists are what really give you GPP, and if you have a nice variety of buildings by mid-game, you can direct your GPP instead of leaving it mostly to chance. For instance, if you need a Great Merchant, just cram your market and grocer full of Merchants, and you probably won't have to wait long. Also, make buildings that raise your happy/health cap in the city (this is where Globe comes in handy, you'll only have to worry about the health limit).
It's more complicated than that, but that's the basics. Welcome to CFC!
