Sound advice.
I generally keep 2 or 3 archers or longbowmen even in the core cities, usually left over from when I've been running the civic that gives the city happiness for having them there, and make sure most of my defenders are on dangerous borders and coasts. Yup yup.
I also don't let a stack go anywhere without two spearmen in early game (and try to get one or two in cities too) as I find quite a few of the AIs fond of horses. Chariots, horse archers and later cavalry/cuirassiers.
On my latest game, I'm Isabella. I had a pretty crummy start, coastal city with a food surplus but on a reasonably small peninsula. I pressed north and found Kublai and knew he'd try to seal me off down there so I expanded fast, planted one city north east where I found copper, and another to the further north west with some minor resources but horses and elephants that I didn't want him to get. It also meant I'd expanded my cultural borders far enough that I wasn't blocked in by him. Then I noticed he'd found the only source of iron for miles, his own stash of copper (at the rearmost part of his civilization) and stone and his own horses!
Disaster.
So I built two hefty stacks of axemen with a couple of spears each in anticipation of those horses. My sole chariot scouting him out didn't show any mounted units, but better to have them and not need them than need them and not have them.
I declared war on him right as Hatty found me (she must be pretty far west) and luckily she didn't mind. I took on her religion of Judaism to keep her sweet, noting her score half mine and declared war on Kublai before he decided to make use of his horses (and because swordsmen and longbowmen were appearing).
I think I waited too long and I made more mistakes. War is distracting. >_<
I dropped the research slider while I marched over to minimize my outgoings and forgot to raise it until after the war. I think that's gonna cost me later. But I wiped him out in around 875AD, found I had nearly a grand in my treasury and promptly sent a settler up into his ex-territory because I razed all his cities due to their poor locations.
I'm building catapults now and I'm gonna finish alphabet to get tech trading and get a few I missed off Hatty (no archery yet, whoops :S). Then I'm gonna aim for whatever gets me courthouses, resettle what used to be Mongolia and see where I can go from there.
To be honest, this is the point where I tend to start going wrong. I'm still learning the tech tree and sometimes find I've missed a vital prerequisite for something by not realising it was necessary. At least Hatty isn't a threat yet so I should have time to build up a better army before going after her.
All in all I'd say this is my best run yet on noble, but still far from ideal. Hatty is friends but too weak to be of any real assistance and I want to wipe her out before she realises she's next. And then the dreaded naval antics, which I'm still rubbish at. ¬¬
Least I have Kublai's iron now. Muwahahaha.
