While it's great fun slaughtering people in 1v1 Feudal War I'd like a few more harder games so I thought I'd give people a better idea of what they should be doing.
First Turns:No matter what game type you are playing go nuts on your first turn. There is always at least 20 neutrals between you and your closest opponent and those little +1 for every 2 territories add up a lot over time. You should get as many of them as you can as quickly as you can. If your opponent is dumb enough to make a go at you chances are almost 99% his forces will be so crushed you can rush down his little line of 1s and have another castle your next turn.
(Special Note: Keep in mind it's +1 for every 2, pushing yourself for 5 or some other odd number is dumb. If you have 3 or 4 left and the next number is odd just wait a turn.)
After That: Once you have everything in your starting territories except the 10s it's usually a good idea to pick a village and go for it. The best one to go for is pretty much top down. (Rhu then Fol then err, that other one) Don't try to compete with an opponent over villages if you have more than one option.
Late Game: Now that you've done this you should start building up near your borders. Don't break your own neutrals though, wait for their patience to wear out, or for your chances to be so good you can afford to rush through to them. Often they are still attacking weird random things at this point or exhausting their armies on neutral 10s for no apparent reason. If your forces are double theirs it's nearly always a good idea to make a push.
(Special Note: Never ever forget that castles can bombard their entire realm. Don't leave any extra armies in their area during a siege if you don't take the castle. You get enough people every turn you can afford to siege again with just your drop.
Profit:Eventually you should win. There is more to it then all that, but that's the basics.
