The golden age benefits can be quite significant for your gold output. I have not played all of these myself, but in my experience Darius I from Persia is an excellent civilization for playing tall and generating gold.
#BRAVE NEW WORLD CIV 5 COST FREE#
Roads/Railroads on hills are free and half cost elsewhere.Unique unit (Nau) can produce gold, once per unit.Gets additional gold per trade route (based on how many different luxury resources you have).Venice is extremely strong for producing gold, with the notable downside that you cannot build Settlers to claim additional land.Unique unit (Merchant of Venice) replaces Great Merchant and gives you double gold for trade missions with City States.Also allows you to hit golden ages more often by giving happiness. Unique building (Satrap's Court) gives more gold.Also, when playing tall, you are more likely to hit more golden ages.) Golden ages last 50% longer (during golden ages, you generate more gold.Unique tile improvement (Kabash) adds gold to desert tiles.Extra gold per trade route with other civilizations.There are several good options for producing a strong economy. Remind them to not do anything to marshes and floodplains as the Polder is one of the better improvements.
Note: since you mention playing with your friends, playing the Dutch can be useful as you can build Polders on your friends' territories. Try to site your cities near oases and Oil resources (though the latter is pretty much luck of the draw until you get Biology) to get that precious +2 Gold per tile. Given that you gain so much gold income from the Bazaar, it's best that you rush it as quickly as possible. The UA allows your trade routes to extend further and the UB is one of the best, if not the best, for gold income. Arabia is most likely your best bet for high gold income without investing a lot in multiple cities. If you're not the empire-building type, getting high gold income will be rather difficult as Brave New World has greatly reduced gold income from tiles to push you to use the new trade route mechanic.
Send out a Legion with every Settler and have them build roads back to the capital once the new City is built. I hope it is helpful to some of you who are learning the game, or just want to use some of the resources on my site.Rome is actually very good for this as one of their UUs, the Legion, can construct roads, allowing you to build and connect far-flung cities without the risk of Workers being captured by Barbarians.
#BRAVE NEW WORLD CIV 5 COST PLUS#
It is my favorite version of the game to date, and i've played all 5 plus some of the others (like Alpha Centauri). Civ 5 is a deep game and I've undertaken a huge project in trying to cover all of it, but thankfully it's still fun even after hundreds of hours of play. You can leave comments on the Guide to let me know what you think or share information to help improve it for future readers. I'm working to cover every single Civ, which will take months of play on my part, so that I can provide valuable information to newcomers and allow veterans to share extra information that I may have left out.
I have a Civ list with detailed information on all Civs with both DLC and all other addons that will help players select their next Civ much better than the in-game interface, which I find is very popular for the game lacks information on unique units and buildings. I'm actively developing a strategy guide to the game, which is now at over 120 pages of pure content. I am sharing my site with the Civ 5 players here to help draw attention to my effort to cover every aspect of Civ 5 gameplay.
