Hey Starch. Ignore the people who are laughing at you and the guy who boasts of winning in 58 minutes; instead of helping you, all they've done is be rude. I can give you a few pointers (FF is my favorite mod in BtS! I play it more than the regular game!), but if you could clarify some of the things you might need help with, I could give you some more detailed advice.
First off, as someone else already mentioned, it's very important to build on more than one planet in each system; cities in FF no longer have a "true" fat cross (the 21 squares inhabitants could work), but instead they are solar systems with planets on which you can build different buildings. For example, in your capital, you can build a Factory on one planet, then a factory on your second planet, and so on (this is done by clicking on the different planets on the right side of the cityscreen, then checking the "Build new improvements on this planet" or whatever button).
Another huge change in FF from the Epic Game is that resources will NEVER (or at least, almost never!) be inside a cities' influence/culture border, and even if it was, you couldn't "work" the square anyway (as mentioned above). Instead, you need a worker (a Construction Ship) to build roads (warp lanes) out to the asteroid field where the resource is (such as Hydrogen or Gold), and build a Starbase (which will consume the worker). Starbases are "units" that will extend your influence across the resource(s) in the asteroid field in a reasonable amount of time (instead of waiting for your cities' influence to get all the way out there!) so you can then have another Construction Ship (the first is consumed in constructing the Starbase) build an Extraction Facility on the resource. Resources are very important, because your cities will very quickly become angry and polluted if you don't get the powerful (+3 happiness/health) happiness and health resources. There are others as well, such as Iron that will allow you to build certain units faster which can be handy, but the happ/health resources should be a priority.
Founding Values (religions) is also a very important aspect to FF, because each Value allows every city where it is present to build a Special Building, like a School of Zealots (Power Value), or a Survival Dome (Survival Value). These Special Buildings are very powerful and important because of their potency, and can mean the difference between winning and losing, happy or rioting cities, a tech lead or being "backward", etc.
Finally, something that helped me out a lot when I was struggling economically (to put it lightly-- my economy had pretty much crashed!): build MagLev Networks on several of your more populous planets (i.e., your planets that can support 2 or 3) and planets that are producing a fair bit of gold already (I believe gas giants produce 6 commerce to begin with!), and then when you can, Commercial Satellites make a HUGE difference (+2 commerce!) and should be applied liberally as well. And if you play like me, never waste time (or more specifically, money!) on Espionage; in FF, in my opinion, it's almost worthless because there are no spies, only the passive espionage missions, and in my experience the AI will almost invariably out-espionage you. *I prepare myself for the arguments over Espionage to commence*
And of course-- don't give up!!! I lost my first few FF games HORRIBLY, but after a while I got the hang of it, and it's now, as I said, my favorite mod! So keep trying, and bring your questions here and I'll do what I can to help.
