Necromancy, I know, but for good reason.
I've been playing this quite a bit lately - having fun with it so far. It makes a really good complement to coding, because you can check on it every 15-30 minutes and perform actions, then go back to whatever you were doing beforehand. I started up in the new World 5 at the behest of an RL friend who's playing, and I'm now level 10, about to break 11. So far I've taken a primarily economic approach. On the SK wiki they advise you not to buy research points early on, but this seemed inherently stupid to me, since with a lot of the technologies you research the benefits will help you a LOT in the early game. My instinct seems to have been correct thus far: I've easily surpassed all of the higher-leveled players in my parish already, not to mention the friend who got me started. I've been upgrading my military as needs require, so I can now support a not-too-shabby army capable of crushing bandit lairs and wolf dens. I've vassalized another player and had him join the unofficial alliance I'm in, and also have a full army of archers stationed in his village (right on the border of my honor circle) so that I can get double the honor from dens/hideouts.
Advice to new players: after getting your economy up and humming, take Forced March up to 8. It is absolutely essential if you want to be competitive about nabbing those lairs.
If anyone starts up in World 5, look me up. I'm Lord Dullard in the parish of Enniscorthy, county of Wexford. I can try to send some supplies and such your way to get your early game going, and probably spare a few troops.
