If you win 1/X games when playing with X civs, its exactly your dificulty.
If you win more, you should go up.
I cant remember the time i was playing on noble, but i dont think i fared better than you at first. Im fairly sure i lost a few Settler games, and theres no shame in that. But i kept learning from my mistakes, and how to avoid them.
Today i am working on getting my win-rate on large 8-civ immortal maps from 40 to 70% (not playing Capac for a principle).
That said, to get a grip on the new level aim for these points:
Leader Choice
.) Creative Leader - Not having to care for stonehenge/monument/religion for culture expand is the bomb. Cheaper buildings also rock.
.) Financial Leader - Best trait hands down. Most boring too, but effective.
.) Aggressive Leader - NOT having to take combat 1 to unlock anti-X promotions is a huuuge bonus.
Stay away from:
.) Protective Leader - Good if played right, might be something for later
.) Philosophical Leader - Same
.) Industrious Leaders - You run in danger of going Wonderwhoring(tm) to the point that you defend the pyramid/stonehenge/oracle city with only a warrior.
.) French Leaders - Nobody likes them french
Civilization Choice
.) Unique Buildings make a difference; most of them anyways. Aim for early UBs, possibly those that dont get obsolete.
.) Unique Buildings that you would have built anyway are good.
Stay away from
.) Civs with really really awesome Unique Units. They can make a difference at Epic and higher, below that they are outdated too quickly.
Never rely on a single concept to win the game, it wont work.
City placement:
Aim for
.) Coastal Cities - More trade routes, more cash, more everything.
.) Flood plains - 3

1

is THE place to settle cottages. Make money AND food, what more can you ask for?
.) Rivers - rivers act like roads in terms of ressource availability within your realm. Saves lots of time NOT having to connect every ressource and city with roads to have access to them.
Stay away from
.) Super production cities with no food. What good are 8 mines if you can only work 1 of them because your city has just


tiles? 3 Hills make a nice Production site, 12 Hills will leave the city starving.
.) Super Gold cities - see above.
.) Avoiding overlapping - Yes, stay away from avoiding it. Overlapping is your friend. Overlapping non-ressource tiles becomes interesting when one of the cities grows to size 20. A city the size of 12 is good enough to seriously fulfill its role, be it income or production. Most of my cities top at 15-18, and then its time for the whip.
Having 2 cities at 10 is generally better than 1 at 15 (which is about the equivalent, growth-wise)
ok, that was long enough.
If you bothered to read through this, i hope you can take some of the advice and become a stronger player, and enjoy the challenge of taking on higher levels.
